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 be
