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

Options

A. `-610 KJ" "mol^(-1)`
B. `-850" "KJ" "mol^(-1)`
C. `+120" "KJ" "mol^(-1)`
D. `+152" "KJ" "mol^(-1)`

Answer

A
