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.
