The reaction A + B --> C has a delta Gr of -20 kJ/mol at 25 C. Starting under standard conditions, one can predict that: A. at equilibrium, the concentration of B will exceed the concentration of A. B. at equilibrium, the concentration of C will be less than the concentration of A. C. at equilibrium, the concentration of C will be much greater than the concentration of A or B. D. C will rapidly break down to A + B. E. when A and B are mixed, the reaction will proceed rapidly toward formation of C.
