• question_answer1) Oxidising power of chlorine in aqueous solution can be determined by the parameters indicated below:

 $\frac{1}{2}C{{l}_{2}}(g)\xrightarrow{\frac{1}{2}{{\Delta }_{diss}}{{H}^{\Theta }}}Cl(g)\xrightarrow{{{\Delta }_{eg}}{{H}^{\Theta }}}C{{l}^{-}}$$(g)\xrightarrow{\frac{1}{2}{{\Delta }_{hyd}}{{H}^{\Theta }}}C{{l}^{-}}(aq)$ The energy involved in the conversion of $\frac{1}{2}C{{l}_{2}}(g)$ to $C{{l}^{-}}(aq)$ (using the data, ${{\Delta }_{diss}}H_{C{{l}_{2}}}^{\Theta }=240\,kJ\,mo{{l}^{-1}},\,{{\Delta }_{eg}}H_{Cl}^{\Theta }=-349$$kJ\,mo{{l}^{-1}},{{\Delta }_{hyd}}{{H}_{C{{l}^{-}}}}=-381\,kJ\,mo{{l}^{-1}})$ will be
