For the reaction 2 A(aq) <---> B(aq) + C(aq), the standard
Gibbs free enthalpy change is 1.47 kJ at 25oC. The initial
concentration of A(aq) is 0.567 M, the initial concentration of
B(aq) is 0.303 M, and the initial concentration of C(aq) is 0.219
M. What would be the concentration of A(aq) (in mol/L) once we
attain equilibrium (we are still at 25oC)?
