WebThe Van 't Hoff equation relates the change in the equilibrium constant, K eq, of a chemical reaction to the change in temperature, T, given the standard enthalpy change, Δ r H ⊖, … WebThe Third Law of Thermodynamics. The third law of thermodynamics defines absolute zero on the entropy scale. Third law: The entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 K). The crystal must be perfect, or else there will be some inherent disorder.
