Oxidising power of chlorine in aqueous solution can be determined by the parameters indicated below : (1)/(2)Cl_(2)(g)overset((1)/(2)Delta_(diss)H^(Theta))rarrCl(g)overset(Delta_(eg)H^(Theta))rarrCl^(-)(g)overset(Delta_(hyd)H^(Theta))rarrCl^(-)(aq)The energy involved in the conversion of(1)/(2)Cl_(2)(g) " to " Cl^(-)(aq)(Using the data,Delta_(diss)H_(Cl_(2))^(Theta)=240 kJ mol^(-1),Delta_(eg)H_(Cl)^(Theta)=-349 kJ mol^(-1),Delta_(hyd)H_(Cl)^(Theta)=-381 kJ mol^(-1)) will be

Answer»

`-610 kJ mol^(-1)`
`-850 kJ mol^(-1)`
`+120 kJ mol^(-1)`
`+152 kJ mol^(-1)`

Solution :`DeltaH=(240)/(2)-349-381`
`=120-349-381=-610kJ//mol`.
