The dissociation vapor pressure of a salt A2B(s) A2ig) + B(g) at 367°C is 208 kPa but at 477°C it has risen to 547 kPa. For the dissociation reaction of A2B(5), calculate (i) the equilibrium constant, (ii) the standard reaction Gibbs energy, (iii) the standard enthalpy, and (iv) the standard entropy of dissociation, all at 422°C. Assume that the vapor behaves as a perfect gas and that A,H° and A,S° are independent of temperature in the range given.
