Understand the concepts of enthalpy (H), entropy (S), free energy (G), and free energy change (ΔG). - ANSWER-Δ-G = favorable/spontaneous (exergonic) Δ+G = not favorable/non-spontaneous (endergonic) ΔG does NOT say anything about rate What is meant by favorability/spontaneity in relation to a chemical reaction? - ANSWER-This refers to what is going to be more likely to happen/form in a chemical reaction. Although entropy is favored by the universe, it isn't seen as often. Every reac...
