We start with a pure sample of A(g). The following equilibrium is established: 2 A(g) <---> B(g) + C(g) The total pressure is 8.66 atm and the temperature is 25.0°C.

The partial pressure of A(g) is 5.28 atm. Calculate the value of the standard Gibbs free enthalphychange (in kJ) for this reaction at 25.0°C.
