Chemistry Question from JEE Main 2023 · 31 January, Shift 1

The enthalpy change for the conversion of 12Cl2(g)→Cl−(aq) is (−) ..... kJ mol−1 (Nearest integer)\frac{1}{2} Cl_2(g) \rightarrow Cl^-(aq) \, is \, (-) \, .....\, kJ\, mol^{-1} \, (Nearest\, integer)

Given: ΔfH∘(Cl2(g))=240 kJ mol−1,ΔgH∘(Cl2(g))=−350 kJ mol−1,ΔhydH∘(Cl−)=−380 kJ mol−1\Delta_{f}H^\circ(Cl_2(g)) = 240 \, kJ\, mol^{-1}, \quad \Delta_{g}H^\circ(Cl_2(g)) = -350 \, kJ\, mol^{-1}, \quad \Delta_{hyd}H^\circ(Cl^-) = -380 \, kJ\, mol^{-1}
