Question

A reaction has ΔG = 0. What does this signify?
Options
A The system is at equilibrium
Correct Answer
B The reaction is irreversible
C The system is exothermic
D The entropy change is zero
Correct Answer

Option A is the correct answer.

Detailed Explanation

When ΔG = 0, the system is at equilibrium. There is no driving force in either direction, and the forward and reverse reaction rates are equal.

Hint

This is the condition for a system in a state of balance, where no net change occurs.
