WebJul 8, 2015 · The Gibbs phase rule tells me that at a substance's triple point, where there are 3 phases in equilibrium, there should be 0 degrees of freedom. Based on my understanding, that means there should be 0 intensive properties that can be varied. When you look at a P-T phase diagram, the triple point is actually a point so the 0 DF makes sense. 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)
