4. Practice Problems and Solutions
Problem 1
Calculate the standard free energy change for the following reaction at 298 K:
$$\textN_2\text(g) + 3\textH_2\text(g) \rightleftharpoons 2\textNH_3\text(g)$$
Given: $$\Delta H^\circ = -92.4 \text kJ/mol$$ $$\Delta S^\circ = -198.7 \text J/(mol K)$$
Solution
The standard free energy change is given by:
$$\Delta G^\circ = \Delta H^\circ
T\Delta S^\circ$$
Substituting the given values, we get:
$$\Delta G^\circ =
- 92.4 \text kJ/mol
- (298 \text K)(-198.7 \text J/(mol K))$$
$$\Delta G^\circ =
33.2 \text kJ/mol$$
5. Test-Taking Strategies for Physical Chemistry ACS Exam
Taking the ACS Practice Exam for Physical Chemistry requires effective test-taking strategies to maximize your score. Here are some tips to consider:
Time Management
Manage your time wisely by allocating an appropriate amount of time to each section of the exam. Prioritize answering questions that you are confident about first.
Guessing
If you are unsure about an answer, make an educated guess. The exam does not penalize for incorrect answers, so it is always worth guessing if you have eliminated some of the choices.
Review and Check
After completing the exam, take some time to review your answers and check for any errors. Make sure to double-check your calculations and ensure that you have answered all the questions.
