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.
A. Statement I and II both are wrong
B. both are correct
C. only I is correct
D. only II is correct
