Sample Questions and Answers from a Typical General Chemistry 2 Final Exam PDF
Question 1: Chemical Equilibrium
Q: Consider the reaction: \( N2(g) + 3H2(g) \leftrightarrow 2NH3(g) \). If the reaction mixture initially contains 1.0 mol of \( N2 \) and 3.0 mol of \( H2 \), and at equilibrium, 0.5 mol of \( NH3 \) is formed, what is the equilibrium constant \( K_c \)?A:
The reaction consumes 0.5 mol of \( N2 \) and 1.5 mol of \( H2 \), producing 1 mol of \( NH_3 \).
Initial concentrations:
- \( [N2]0 = 1.0\, M \)
- \( [H2]0 = 3.0\, M \)
At equilibrium:
- \( [N_2] = 1.0 - 0.5 = 0.5\, M \)
- \( [H_2] = 3.0 - 1.5 = 1.5\, M \)
- \( [NH_3] = 0.5\, M \)
\( Kc = \frac{[NH3]^2}{[N2][H2]^3} = \frac{(0.5)^2}{(0.5)(1.5)^3} = \frac{0.25}{0.5 \times 3.375} = \frac{0.25}{1.6875} \approx 0.148 \)

Question 2: Thermodynamics
Q: Calculate the standard Gibbs free energy change (\( \Delta G^\circ \)) at 25°C for the reaction: \( 2NO2(g) \leftrightarrow N2O_4(g) \) given \( \Delta H^\circ = -58\, kJ/mol \), \( \Delta S^\circ = 176\, J/(mol \cdot K) \).A:
Convert \( \Delta S^\circ \) to kJ: \( 176\, J/(mol \cdot K) = 0.176\, kJ/(mol \cdot K) \).
Temperature \( T = 25°C = 298\, K \).
Calculate \( \Delta G^\circ \):
\( \Delta G^\circ = \Delta H^\circ - T \Delta S^\circ \)
\( = -58\, kJ/mol - 298\, K \times 0.176\, kJ/(mol \cdot K) \)
\( = -58\, kJ/mol - 52.45\, kJ/mol = -110.45\, kJ/mol \)
