1. Circle the correct answer: a. For a reaction to occur spontaneously, which must have the higher free energy: (reactants or products or equal.) b. A reaction must occur spontaneously if AH is (positive or negative) and AS is (positive or negative.) c. For this reaction, the entropy (increases or decreases): H2(9) 2H() -> d. The equilibrium constant for A B+C is 10-5, therefore, when all concentrations are 1 M (A spontaneously → B+C or B + C spontaneously ►A) and the change in free energy is (positive or negative.)
