When the hydrate CaSO4 . 2 H₂O(s) is heated the reaction

When the hydrate CaSO4 . 2 H₂O(s) is heated the reaction below occurs. CaSO4 . 2 H₂O(s) CaSO4(s) + 2 H₂O(g) a) Using the data in the table below, calculate the value of AG, in kJ/mol, for the reaction at 298 K. Substance ΔGt (kJ/mol) CaSO4 . 2 H₂O(s) -1775 CaSO4(g) -1310 H₂O(g) -221 b) Using the value you calculated for AG, would this reaction be thermodynamically favorable? Given that the value of AH° for the reaction at 298 K is +105 kJ/mol, calculate the value of ΔS° for the reaction at 298 K. Include units with your answer.
