Match the following. -Δ_rG°

Question

Match the following. -Δ_rG° < 0

Quizplus · Accepted Answer

The equation ΔG° = -nF E° shows that if ΔG° is negative, then E° must be positive for the reaction to be spontaneous. Δ_rG° is the standard entropy change of the reaction, and if it is negative, it means that the reaction tends towards more order and less disorder, which is not favorable. A negative Δ_rG° results in a positive ΔG°, which indicates that the reaction is not spontaneous. Therefore, for a spontaneous reaction, E° is positive, which means that E°_cell > 0. Hence, the best choice is C.
