At `25^(@)C`, for the reaction, `H^(+)(aq)+OH^(-)(aq)toH_(2)O(l),DeltaH^(0)=-57.3kJ*mol^(-1)`. If the ionisation enthalpy of HCN in water by 45.2 `kJ*mol^(-1)`, then the standard heat of reaction (in `kJ*mol^(-1)`) for the reaction, `HCN(aq)+NaOH(aq)to NaCN(aq)+H_(2)O(l)`, in dilute aqueous solution is-
