Read following statement(s) carefully and select the right option : (I) The enthalpy of solution of CaCl_(2). 6H_(2)O in a large volume of water is endothermic to the extent of 3.5 kcal/mol. If DeltaH=-23.2 " kcal" for the reaction, CaCl_(2)(s)+6H_(2)O(l)rarrCaCl_(2).6H_(2)O(s) then heat of solution of CaCl_(2) (anhydrous) in a large volume of water is - 19.7 kcal/mol (II) For the reaction 2Cl(g)rarrCl_(2)(g) , the sign of DeltaH and DeltaS are negative.
