1 Which one of the following statements about a reaction is not correct? If all are correct, respond (E). Remember: G = G o + RT ln(Q). A) If G > 0, then products will be converted to reactants until equilibrium is reached. B) At equilibrium, G = 0. C) The equilibrium constant, K, is determined by the standard free energy change, G o , for the reaction. D) The equilibrium constant, K, is determined by the rate constants for the elementary reactions in a reaction mechanism. E) All the above (A – D) are correct. 2 Identify whether a reaction is reactant favored or product favored from the magnitude of the equilibrium constant. K involves [products] exp divided by [reactants] exp If K >>1, G o <<0 then product favored If K<< 1, G o >>0 then reactant favored If K ~ 1, G o ~0 then both products & reactants are present in significant amounts at equilibrium. See MSJ p. 686 – 688. o G RT Ke Reactants Products
