CHM 101 Chemical Thermodynamics Objective Question

Question

If Q < K, what is the sign of ΔG and which direction is spontaneous?
Options
A ΔG < 0, forward reaction is spontaneous
Correct Answer
B ΔG > 0, reverse 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 spontaneous. The reaction proceeds toward products.

Hint

The notes explain this case.
