Assignment Help:

Desiccants (drying agents) can often be regenerated by heating.  A desiccant 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?
