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. WebFor example, when Mr. Khan was talking about a spontaneous Gibbs free energy process - if delta H (enthalpy) was positive and delta S (entropy) was positive, the temperature would need to have a "High T" or high enough to make delta G (Gibbs free energy) negative overall and thus a spontaneous process. So, what Mr. Khan is describing regarding ...
