ΔGsys = ΔHsys – TΔSsys. Where, ΔGsys = Gibbs energy change of the system. ΔHsys = enthalpy change of the system. ΔSsys = entropy change of the system. T = Temperature of the system. This is known as the Gibbs equation. For a spontaneous process, the total entropy change, Δ S total is always greater than zero.

WebHess's law of constant heat summation, also known simply as Hess' law, is a relationship in physical chemistry named after Germain Hess, a Swiss-born Russian chemist and physician who published it in 1840. The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the sequence of steps taken.. … WebThe first and second laws of thermodynamics and the core concepts of enthalpy, entropy and Gibbs free energy are introduced in this simulation. You can play around with the energy levels of reactants and products on a virtual energy surface to learn about endothermic and exothermic reactions.
