4. For the reaction 2A(g) + B(g) → 4C + 3D, AG is 456.2 kJ/mol at 25.0°C. a. Write the Q expression for this reaction. b. Calculate the Q when the concentration of [A] = 0.432 M, (B] = 1.234 M, [C] = 0.3367 M and [D] = 0.250 M. c. Calculate the nonstandard Free Gibbs Value in kl/mol at 25.0°C d. What should be done to the concentrations of C and D to make the reaction go from being nonspontaneous to spontaneous? (Increase or decrease) Explain your answer. (Assume the concentration of A and B remain at 0.432 M and 1.234 M)
