Estimate the temperature at which the equilibrium constant for CuSO45H2O(s) CuSO4(s) + 5H2O(g) become 1; assume pH2O = 1 bar, and rH and rS dont

Estimate the temperature at which the equilibrium constant for CuSO45H2O(s) CuSO4(s) + 5H2O(g) become 1; assume pH2O = 1 bar, and rH and rS dont vary significantly over the temperature range of interest and can be treated as constant. Given standard enthalpy change of formation (fH ) for CuSO4(s), H2O(g), and CuSO45H2O(s) is -771.36 kJ/mol, -241.82 kJ/mol, and -2279.7 kJ/mol, respectively. The molar standard entropy change ( ) for CuSO4(s), H2O(g), and CuSO45H2O(s) is 109 J/molK, 188.83 J/molK, and 300.4 J/molK, respectively.
