Question: 101

11. Which of the following statements is true of process that is spontaneous in the forward direction?

A. ΔG > 0 and K_eq > Q
B. ΔG > 0 and K_eq < Q
C. ΔG < 0 and K_eq > Q
D. ΔG < 0 and K_eq < Q

Correct Answer: C

Explanation:

For a process to progress forward spontaneously, Q must be less than K_eq and will therefore have a tendency to move in the direction toward equilibrium. A spontaneous reaction's free energy is negative by convention.
