A solid exists in two forms that is A and B and their densities are 3.5155g/cm3 and 2.2670g/cm3, respectively. Analyze the pressure at which the two forms of the solid are in equilibrium at 25oC when the standard Gibbs energy change for the reaction A - B is 240kJ/kg. Suppose that the volume change in going from A to B is independent of the pressure.
