Explanation:
Gibbs free energy of a reaction (
Δ
G ) is the change in free energy of a system that undergoes the chemical reaction. It is the energy associated with the reaction, which is available to do some useful work. If ΔG<0
, then the reaction can be utilized to do some useful work. If
ΔG>0
, then work has to be done on the system or external energy is required to make the reaction happen. ΔG=0 when the reaction is at equilibrium and there is no net change taking place in the system.
