Lecture 37: Gibb's Free Energy

standard molar entropy

(S°) the entropy of one mole of a substance at standard state conditions

second law of thermodynamics

states that heat cannot move from a reservoir of lower temperature to a reservoir of higher temperature in a cyclic process

Gibb's Free Energy

(∆G) a quantity used to measure the maximum amount of work done in a thermodynamic system when the temperature and pressure are kept constant; ∆G[sys] = ∆H[sys] - T∆S[sys]

standard free energy of reaction

(∆G°[rxn]) the free energy change for a reaction when it occurs under standard-state
