Question - A reaction has a standard free-energy change of -4.78 kJ/mol at 25 degree 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 above change if the reaction had a standard free-energy change of +4.78 kJ/mol? All concentrations would be higher. All concentrations would be lower. There would be no change to the answers. There would be less A and B but more C. There would be more A and B but less C.
Solve the questions given above in detail thus I will get good grades in exams
