Question

Oxidising power of chlorine in aqueous solution can be determined by the parameters indicated below:
${1 \over 2}C{l_2}(g)$ $$\buildrel {{1 \over 2}{\Delta _{diss}}{H^\Theta }} \over \longrightarrow $ $Cl(g)$ $\buildrel {{\Delta _{eg}}{H^\Theta }} \over \longrightarrow $ $C{l^ - }(g)$ $\buildrel {{\Delta _{Hyd}}{H^\Theta }} \over \longrightarrow $ $C{l^ - }(aq)$$
(Using the data, ${\Delta _{diss}}H_{C{l_2}}^\Theta $ = 240 kJ/mol, ${\Delta _{eg}}H_{Cl}^\Theta $ = -349 kJ/mol, ${\Delta _{hyd}}H_{C{l^ - }}^\Theta $ = - 381 kJ/mol) will be :

+152 kJ mol⁻¹

−610 kJ mol⁻¹

−850 kJ mol⁻¹

+120 kJ mol⁻¹
