Consider the given data: (a) {\HCl}( {\g})+10 {\H}_2 {\O}( {\l}) \rightarrow {\HCl} .10 {\H}_2 {\O} ∆ {\H}=-69.01 {\kJ} {\mol}{ }^{-1} (b) {\HCl}( {\g})+40 {\H}_2 {\O}( {\l}) \rightarrow {\HCl} .40 {\H}_2 {\O} ∆ {\H}=-72.79 {\kJ} {\mol}{ }^{-1} Choose the correct statement: [4 Apr 2025 Shift 2]

Correct Answer is : The heat of dilution for the HCl(HCl.10H2O. to HCl.40H2O ) is 3.78kJmol−1.

Dissolution of gas in water is an endothermic process.

The heat of solution depends on the amount of solvent.

The heat of formation of HCl solution is represented by both (a) and (b).

The heat of dilution for the {\HCl} ( {\HCl} .10 {\H}_2 {\O}. to {\HCl} .40 {\H}_2 {\O} ) is 3.78 {\kJ} {\mol}^{-1}.
