CHM 101 Chemical Thermodynamics Objective Question
Take CBT

Question

If Q > K, what is the sign of ΔG and which direction is spontaneous?
Options
A ΔG > 0, forward reaction is nonspontaneous, so reverse reaction is spontaneous
Correct Answer
B ΔG < 0, forward reaction is spontaneous
C ΔG = 0, system at equilibrium
D ΔG cannot be determined
Correct Answer

Option A is the correct answer.

Detailed Explanation

If Q > K, ln(Q/K) > 0, so ΔG > 0, and the forward reaction is nonspontaneous. The reaction proceeds in reverse (toward reactants).

Hint

The notes explain this case.
