What is Gibbs free energy?

In thermodynamics, the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum reversible work that may be performed by a thermodynamic system at a constant temperature and pressure. This maximum can be attained only in a completely reversible process.

How equilibrium constant with respect to the Gibbs free energy?

1. When ΔG0 = 0, then, Kc = 1

2. When, ΔG0 > 0, i.e. positive, then Kc < 1, in this case reverse reaction is feasible showing thereby a less concentration of products at equilibrium rate.

3. When ΔG0 < 0, i.e. negative, then, Kc > 1; In this case, forward reaction is feasible showing thereby a large concentrations of product at equilibrium state.
