WebApr 14, 2024 · Free energy minimization, equal to entropy maximization, turns out to be the second law of thermodynamics when derived from statistical physics of open systems. This many-body theory is based on the atomistic axiom that everything comprises the same fundamental elements known as quanta of action; hence, everything follows the same law. WebGibbs free energy is equal to the enthalpy of the system minus the product of the temperature and entropy. The equation is given as; G = H – TS Where, G = Gibbs free energy H = enthalpy T = temperature S = entropy OR or more completely as; G = U + PV – TS Where, U = internal energy (SI unit: joule) P = pressure (SI unit: pascal) WebThe maximum entropy principle: For a closed system with fixed internal energy(i.e. an isolated system), the entropyis maximized at equilibrium. The minimum energy principle: For a closed system with fixed entropy, the total energyis minimized at equilibrium.
