Webequation for Gibbs free energy is: where ∆H is the enthalpy, T is absolute temperature, and ∆S is entropy. The enthalpy ( ∆H) is a measure of the actual energy that is liberated when the reaction occurs (the “heat of reaction”). If it is negative, then the reaction gives off energy, while if it is positive the reaction requires energy.
