For the reaction 2 A(aq) <---> B(aq) + C(aq), the standard Gibbs free enthalpy change is 1.69 kJ at 25oC. The initial concentration of A(aq) is 0.549 M, the initial concentration of B(aq) is 0.327 M, and the initial concentration of C(aq) is 0.234 M. What would be the concentration of A(aq) (in mol/L) once we attain equilibrium (we are still at 25oC)?
