A(aq) + B(aq) ⇌ C(aq)
has a standard free-energy change of -5.07 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 above change if the reaction had a standard free-energy change of +5.07 kJ/mol?
•All concentrations would be higher
•There would be no change to the answers.
•All concentrations would be lower.
•There would be more A and B but less C.
•There would be less A and B but more C>
