A reaction A(aq)+B(aq)C(aq) has a standard freeenergy change of 4.75 kJ/mol at 25 C. What are the concentrations of A, B, and C at equilibrium if, at the beginning of the reaction, their concentrations are 0.30 M, 0.40 M, and 0 M, respectively? How would your answers change if the reaction had a standard freeenergy change of +4.75 kJ/mol? 1) All concentrations would be higher. 2)There would be more A and B but less C. 3)All concentrations would be lower. 4)There would be no change to the answers. 5) There would be less A and B but more C.
