why the gibbs free energy is such a useful state function?​

Answer:

•Gibbs Energy is a state function defined as G=H-TS. The practical utility of the Gibbs function is that ΔG for any process is negative if it leads to an increase in the entropy of the world. Thus spontaneous change at a given temperature and pressure can only occur when it would lead to a decrease in G.

•When a system changes from an initial state to a final state, the Gibbs free energy (ΔG) equals the work exchanged by the system with its surroundings, minus the work of the pressure force.Therefore, Gibbs free energy is most useful for thermochemical processes at constant temperature and pressure.
