Q1

Consider the given data:
(a) \(\mathrm{HCl}(\mathrm{g})+10{\mathrm{H}}_{2}\mathrm{O}(\mathrm{l})\to \mathrm{HCl}.10{\mathrm{H}}_{2}\mathrm{O}\mathrm{ΔH}=-69.01\mathrm{kJ}{\mathrm{mol}}^{-1}\)
(b) \(\mathrm{HCl}(\mathrm{g})+40{\mathrm{H}}_{2}\mathrm{O}(\mathrm{l})\to \mathrm{HCl}.40{\mathrm{H}}_{2}\mathrm{O}\mathrm{ΔH}=-72.79\mathrm{kJ}{\mathrm{mol}}^{-1}\)
Choose the correct statement :

[JEE Main 2025, 4 Apr (Shift 2)]

a

Dissolution of gas in water is an endothermic process

b

The heat of solution depends on the amount of solvent.

c

The heat of dilution for the \(\mathrm{HCl}\left(\mathrm{HCl}\cdot 10{\mathrm{H}}_{2}\mathrm{O}\right.\) to \(\mathrm{HCl}.40{\mathrm{H}}_{2}\mathrm{O}\) ) is \(3.78\mathrm{kJ}{\mathrm{mol}}^{-1}\).

d

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