Question

Which of the following is consistent with a reaction that proceeds spontaneously in the reverse direction (assume all variables are in terms of the forward direction only)?

A. ΔG° = 0, Q = K
B. ΔG > 0, Q > K
C. ΔG° > 0, Q = K
D. ΔG < 0, Q > K
E. ΔG > 0, Q < K

Answer 1

B. ΔG > 0, Q > K

Step-by-step explanation:

For reverse reaction to take place Q should be greater than K

Since reverse reaction should be spontaneous, forward reaction should be non spontaneous.

So, for forward reaction, ΔG > 0

Hence, the correct answer is B
