A reaction A(aq)+B(aq)↽−−⇀C(aq)A(aq)+B(aq)↽−−⇀C(aq) has a standard free‑energy change of −3.76 kJ/mol−3.76 kJ/mol at 25 °C.25 °C....

A reaction

A(aq)+B(aq)↽−−⇀C(aq)A(aq)+B(aq)↽−−⇀C(aq)

has a standard free‑energy change of −3.76 kJ/mol−3.76 kJ/mol at 25 °C.25 °C.

What are the concentrations of A,A, B,B, and CC at equilibrium if, at the beginning of the reaction, their concentrations are 0.30 M,0.30 M, 0.40 M,0.40 M, and 0 M,0 M, respectively?
