Entropy-driven process, Chemistry

Dessicants(drying agents) can often be regenerated by heating.  A dessicant that is commonly regenerated is CaSO4.2H2O:                                                                      

CaSO4.2H2O(s) → CaSO4(s) + 2H2O(g)


    Ho = 25.1 kJ/mol; ?So = 69.3 J/molK

       Regeneration is carried out at 250 oC.

(a)    What is the ?Go for this reaction?

(b)   What is the equilibrium constant at 25 oC?

(c)    What is the ratio K250 C/K25C?

(d)   What is the equilibrium constant at 250 oC

(e)    Is regeneration of this dessicant an enthalpy- or entropy-driven process?  Explain your answer.
