The standard enthalpy change of a reaction is equal to the sum of the standard enthalpies of formation of the products minus the sum of the standard enthalpies of formation of the reactants.
DH = = [ DH(H2SO4) + 2x D H(HCl) ] - [DH(SO2Cl2) + 2 x D H(H2O) ]
= [ -814 + 2 x -92] - [ -364 + 2 x -286 ] = -62 kJ
