Concept Introduction:
Equilibrium constant: The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium.
Gibb’s free energy: The Gibb’s free energy also termed as the available energy; is the thermodynamic potential that is minimized when a system reaches chemical equilibrium at constant and temperature.
