A reaction A(aq)+B(aq) = C(aq) has a standard free-energy change of –4.18 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? [A] = M [B] = M [C] = M How would your answers change if the reaction had a standard free-energy change of +4.18 kJ/mol? There would be no change to the answers. There would be less A and B but more C. All concentrations would be lower. There would be more A and B but less C. All concentrations would be higher.
