Science > Chemistry > Chemical Equilibrium > Gibb’s Energy and Chemical Equilibrium Gibb’s Energy or Free Energy: Gibb’s energy or free energy is a thermodynamic function which helps us in the development of a criterion of spontaneity or feasibility of a process. It refers to the capacity of the system to do useful work. Gibb’s […]

Science > Chemistry > Chemical Thermodynamics and Energetics > Gibb’s Energy and Spontaneity The Concept of Gibb’s Free Energy (G): By the second law of thermodynamics, STotal = ΔSSystm + ΔSSurroundings Thus to decide spontaneity of the process we have to determine the change in entropy of the system and the change in entropy of the surroundings.
