- Not only will you excel on the free-response section, but you'll also know the material so well that the multiple-choice questions will be a piece of cake. In this article, I'll tell you all about the free-response section of the exam, give you some tips on how to solve AP Chemistry FRQs, and go through a couple of sample problems from recent exams so you can get a feel for what they're like! Your test dates, and whether or not your tests will be online or on paper, will depend on your school. The free-response section of the AP Chemistry exam seems intimidating because it's longer than free-response sections on most other AP tests, and it includes lots of calculations and experiments that you have to interpret.
- The most important thing you can do is remain calm and stay focused and methodical in your approach to each question. It's not as scary or difficult as it looks if you've prepared well for the test and use your common sense! Here's an overview of the format of the free-response section: minutes 1 hour 45 minutes Calculator use permitted Three long-response worth 10 points each Four short-response worth 4 points each The long-response questions always come first! You'll be tested on the following skills which may be tied to any topic in the AP Chemistry curriculum : Experimental design Analyzing real lab data to identify patterns and explain phenomena Creating or analyzing diagrams of molecules and atoms to explain observations Translating between different representations of data Following logical steps to analyze and solve problems OK, that all makes sense, but how exactly do you solve these long, complicated questions? My first piece of advice is not to feel obligated to do the questions in order!
- Take a couple of minutes no more than at the beginning of the section to look through everything and decide which question you want to tackle first. It's best to start with your strengths so you'll have more time at the end for challenging questions. You should spend a maximum of 20 minutes on each long free-response question and 10 minutes on each short free-response question. Keep an eye on the time so it doesn't get away from you! Here are some basic steps you should take to solve free-response questions: Step 1: Figure Out What You Know First, assess the information the question gives you. It can be confusing to extract the data that's embedded in the introduction over and over again as you go through different parts of the question. Make things easier for yourself by writing down the values you're given next to the question so that they're easily accessible when you need them. You should also take time to understand at least on a general level the experiment being described so that you don't feel confused and overwhelmed when you start reading the question.

Step 2: Dive Into the Question For each part of the question, read the instructions and ask yourself the following: Do you need to do any calculations? Decide which equations you'll need if applicable , and write them down. Do the necessary calculations based on the numbers you extracted in the previous step and any numbers you were given in this part of the question. Make sure you show your work! Don't erase your calculations, and double-check everything to make sure you have the correct units and your answer makes sense logically.- Does the question ask you to justify or explain your answer? If so, don't ignore these instructions. In many cases, you'll only get points for your answer if you can explain it adequately. Use concrete evidence to back up your response we're talking hard data. Even if something seems obvious to you, spell it out as clearly as possible to ensure that you earn those points! Do you need to draw a diagram? Even though neither of the free-response questions I'll go over in the next section requires this, some questions will ask you to draw diagrams.
- For example: If you have to answer a question like this, try to be as clear as possible. Draw out your answer on scrap paper first if you feel unsure so that the final product is neat and unambiguous. Here's the answer, by the way: Step 3: Double Check Look back at the question to make sure you didn't miss anything or leave out any explanations.
- Reread each part and connect it directly to its corollary in your response so you're scooping up all the points you possibly can! You should also walk through how you found each answer to make sure you didn't make any weird errors you missed the first time around. Finally, check again for appropriate units. Errors in unit conversion are common silly mistakes that are really, really frustrating if you knew how to do the problem correctly otherwise. Did you remember to convert milliliters to liters? AP Chemistry FRQ Examples I'll go through the solution process for a sample question of each type so you can get a better idea of what the test will be like. Notice that these questions look complex and overwhelming at first, but if you stay calm and break them down methodically, they don't end up being that bad!
- Here's a sample long free-response question from the exam: There's a ton of information here, so let's start from the beginning. What we know from the short intro is that the pH of a 0. There's also an equation that shows how the acid reacts with water and which products are created by this reaction. Now we're ready to tackle part a : Where's the conjugate acid-base pair in the equation? Conversely, the water in the first half of the equation is a base that becomes an acid when it picks up the hydrogen atom from the propanoic acid. To get this point, you would need to label each compound indicating which is the acid and which is the base.
- Always read instructions carefully, or you may lose out on points - I can't say this enough! Let's move onto part b : What's the value of Ka for propanoic acid at the temperature indicated in the question? We can find that value using this other equation from the formula sheet: This means:.

How is oedipus not a tragic hero The following section consists of Chemistry Multiple Choice questions on Chemical Engineering Thermodynamics. You have already completed the quiz before. Hence you can not start it again. Introduction into chemistry. Chemistry is a branch of science that studies the composition and properties of matter and the changes it undergoes. Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other.- They have 75 multiple-choice questions there are now 60 and six free-response questions there are now seven. There are also five answer choices for each multiple-choice question, whereas now there are only four. The old AP Chemistry exam emphasized calculations and factual knowledge over a strong understanding of fundamental concepts and mastery of scientific practices. The questions on these tests will still help you practice your skills; just make sure you also use more recent materials for an accurate preview of what to expect on test day.
- Current AP Chemistry Course and Exam Description multiple choice practice included Go to page of this course description to review sample multiple-choice and free-response questions for the current exam. This is not a full practice test it only has 15 multiple-choice questions and two free-response questions total , but it's directly from the College Board, so it's the most accurate and up-to-date representation of the format and content of the test. Free-Response Questions and These free response questions are from the most up-to-date version of the test. I would advise you to save most of them for later on in the year when you're more serious about practicing for the real AP exam. There are seven questions from each year.
- As I mentioned in my description of the out-of-date practice tests above, you'll notice that there used to be six free-response questions on the test instead of seven. You should also know that the questions that ask you to write balanced equations are not on the new version of the test doesn't mean they're not good practice, though!
