Chapter 1 roblems Problems • Book (Ch. 1, prob. 7) onsider a reaction with =15 kJ/mol and =50 J/mol/K Is the reaction Consider a reaction with H1 5 kJ/mol and S5 0 J/mol/K. Is the reaction spontaneous (a) at 10 o C, (b) 80 o C? Recall, G= H-T S, and if G<0, reaction is spontaneous. (a) G=15 kJ/mol - (273+10)K x 50 J/mol/K x 1 kJ/1000 J = 0.85 kJ/mol NO (b) G=15 kJ/mol - (273+80)K x 50 J/mol/K x 1 kJ/1000 J = -2.65 kJ/mol YES 2
Chapter 1, book #9 • Calculate G o ’ for the reaction A + B C + D at 25 o C when the equilibrium concentrations of [A] = 10 M, [B] = 15 M, [C] = 3 [D ]=5 Is the reaction exergonic or endergonic under M, [D] = 5 M. Is the reaction exergonic or endergonic under standard conditions?
