To determine the value of for the reaction , we need to consider the bond enthalpies of the bonds broken and formed during the reaction.In the reaction, the bonds broken are:- 2 H-H bonds in - 1 O=O bond in The bonds formed are:- 4 O-H bonds in The calculation for is: Therefore, the correct calculation is .
