2. Decide whether each of the following statements is true or false. If false, rewrite it to make it true. a. Entropy of the universe increases in all spontaneous reactions. wo False If entropy is bw enough it con be spontaneous, b. Reactions with a negative free energy change (A-Gº <0) are product-favored and occur with rapid transformation of reactants to products. True c. An exothermic reaction will always be spontaneous.

Justify the following sentences by answering (T) for TRUE or (F) for FALSE. (1 mark each) AE is independent on the initial and final state of a system. The sum of entropy changes of the system and surroundings is always positive. The ratio of numerical values of partial pressures of the reaction participants is unitless. Q is small if products pressures are small, a large Q means a negative or good (favorable) contribution to the free energy For pure solids...
