If the free energy change for a reaction for a reaction is zero, it means
A. the reaction is spontaneous
B. the reaction is endothermic
C. the reaction is exothermic
D. the reaction is at equilibrium
If the free energy change (ΔG) for a reaction is zero, it means the system is in a state where there is no net change occurring.
Explanation:
When ΔG < 0, the reaction is spontaneous.
When ΔG > 0, the reaction is non-spontaneous.
When ΔG = 0, the reaction has reached equilibrium, meaning the forward and backward reactions occur at the same rate.
Correct Answer:
D. the reaction is at equilibrium
