Enthalpy is an extensive property. In general, if enthalpy of an overall reaction A rarr B along one route is Delta_(r) H " and Delta_(r) H_(1), Delta_(r) H_(2), Delta_(r) H_(3) ..... Represent enthalpies of intermediate reactions leading to product B. What will be the relation between Delta_(r)H overall reaction and Delta_(r)H_(1), Delta_(r)H_(2) ... etc for intermediate reaction.

Enthalpy is an extensive property.In general, if enthalpy of an overall reaction A to B along one route is Delta_(r)H and Delta_(r)H_(1) + Delta_(r)H_(2) + Delta_(r)H_(3) ... Represent enthalpies of intermediate reactions leading to product B.What will be the relation between Delta_(r)H for overall reaction and Delta_(r)H_(1), Delta_(r)H_(2) ....etc, for intermediate reactions.
