Free energy change for a reversible process is

Explanation

n a reversible process, the system and its surroundings can spontaneously interconvert between two states. This means the reaction can proceed in both the forward and reverse directions without any external intervention.The free energy change (ΔG) is a key thermodynamic parameter that determines the spontaneity of a process. It relates the enthalpy change (ΔH), entropy change (ΔS), and temperature (T):ΔG = ΔH - TΔSFor a reversible process at equilibrium, the free energy change is zero:ΔG = 0This indicates that the forward and reverse reactions occur at equal rates, resulting in no net change in the system. The system and its surroundings are in a state of dynamic equilibrium.
