A (aq) + B (aq) ⇌ C (aq)
has a standard free-energy change of -3.21 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 above change if the reaction had a standard free-energy change of +3.21 kJ/mol?
(a) There would be no change to the answers.
(b) All concentrations would be lower.
(c) All concentrations would be higher.
(d) There would be less A and B but more C.
(e) There would be more A and B but less C.
