Detailed explanation-1: -Gibbs free energy, denoted G, combines enthalpy and entropy into a single value. The change in free energy, G, is equal to the sum of the enthalpy plus the product of the temperature and entropy of the system.
Detailed explanation-2: -The Gibbs free energy of a system at any moment in time is defined as the enthalpy of the system minus the product of the temperature times the entropy of the system. The Gibbs free energy of the system is a state function because it is defined in terms of thermodynamic properties that are state functions.
Detailed explanation-3: -∆S is the change in entropy (disorder) from reactants to products. R is the gas constant (always positive) T is the absolute temperature (Kelvin, always positive)
