1.	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))(rarr)Cl(g)overset(DeltaH_(Eg)^(Theta))(rarr)` `Cl^(-)(g)overset(Delta_(hyd)H^(Theta))(rarr)Cl^(-)(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)=240KJ mol^(-1)`) `Delta_(Eg)H_(Cl)^(Theta)=-349KJmol^(-1)` , `Delta_(Eg)H_(Cl)^(Theta)=-381KJmol^(-1)`) will beA. `+152c `B. `-610KJmol^(-1)`C. `-850KJmol^(-1)`D. `+120KJmol^(-1)`
Answer» Correct Answer - D `(1)/(2)Cl_(2)(g)rarrCl^(-)(aq)` `DeltaH=(1)/(2)DeltaH_(diss)(Cl_(2))+DeltaH_(EA)Cl+DeltaH_(hyd)(Cl^(-))` `=(240)/(2)-349-381=-610KJmol^(-1)`
