CHM 471 BIOPHYSICAL CHEMISTRY I EXAM 1 REVIEW Gibbs Free Energy - ANS-ΔG = ΔH-TΔS ΔG = -TΔS_total ΔG is a measure of the maximal, non-expansion work a system can perform. Entropy change (ΔS) - ANS-ΔS = q_rev/T Entropy change for physical or chemical transformation approaches 0 as T -> 0. Entropy of all perfectly crystalline substances are the same at T = 0 K, and are equal to 0. Carnot Cycle efficiency - ANS-Ɛ = -w_cycle/q = (Th-Tc)/Th Maximum eff...
