Question

Oxidising power of chlorine in aqueous solution can be determined by the parameters indicated below: 1 2 Cl ₂( ~g ) 1 2 _ ass H ^ Cl ( g ) _ eg H^ Cl ⁻( g ) _ m on ^ H^ ^ Cl ⁻( aq ) . The energy involved in the conversion of 1 2 Cl ₂( ~g ) to Cl ⁻( g ) (using the data, . _ diss H_ Cl ₂ ^ =240 kJmol ⁻¹, _ eg H_ cl ^ =-349 kJmol ⁻¹, _ hyd H _ Cl ^ =-381 kJmol ⁻¹ ) will be
