Gibbs free energy change calculator

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) WebSo, K, the equilibrium constant, is equal to 2.7 times ten to the negative six. So, when delta-G zero is positive, when the standard change in free energy is positive, let's write this one down. So, when delta-G zero is …
