Sample Practice Questions for General Chemistry 2 Below are example questions to illustrate the types of problems you may encounter on the ACS exam: Question 1: Thermodynamics A reaction has ΔH° = -50 kJ/mol and ΔS° = 100 J/(mol·K). At what temperature does the reaction become spontaneous? Answer: Convert ΔS° to kJ: 100 J/(mol·K) = 0.1 kJ/(mol·K) Use ΔG° = ΔH° - TΔS°: Set ΔG° = 0 for spontaneity: 0 = -50 kJ - T(0.1 kJ/K) T = 50 kJ / 0.1 kJ/K = 500 K Therefore, the reaction becomes spontaneous at temperatures above 500 K. Question 2: Chemical Kinetics The rate law for a reaction is rate = k[A]^2[B]. If the concentration of A is doubled and B remains constant, how does the reaction rate change? Answer: Rate is proportional to [A]^2: Doubling [A] doubles it to 2[A], so: New rate = k(2[A])^2[B] = k×4[A]^2[B] = 4 × original rate The reaction rate increases by a factor of 4. Question 3: Electrochemistry Calculate the standard cell potential for a galvanic cell composed of a zinc electrode and a copper electrode, given the standard reduction potentials: - Zn²⁺ + 2e⁻ → Zn(s): -0.76 V - Cu²⁺ + 2e⁻ → Cu(s): +0.34 V Answer: Standard cell potential, E°cell = E°cathode - E°anode Cathode (reduction of Cu²⁺): +0.34 V Anode (oxidation of Zn): -(-0.76 V) = +0.76 V E°cell = 0.34 V + 0.76 V = +1.10 V The cell potential is +1.10 V, indicating a spontaneous reaction. Additional Tips for Maximizing Your Practice Effectiveness 1. Create a Study Schedule - Dedicate specific days for practicing different topics. - Mix problem-solving with concept review to maintain engagement. 2. Use Multiple Practice Tests - Gradually increase difficulty. - Simulate different testing conditions to prepare for unexpected scenarios. 4 3.
