For the 2A (aq) <---> B (aq) + C (aq) reaction, the standard free enthalpy change is 1.49 kJ at 25oC. The initial concentration of A is 0.569 M, the initial concentration of B is 0.335 M, and the initial concentration of C is 0.237 M. At equilibrium (we are still at 25oC), what will be the concentration of A ( aq) (in mol / L)?
