1.	Enthalpy is an extensive property. In general, if enthalpyof an overall reaction A rarr B alongone routeisDelta_(r) H and 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 Delta_(r)H_(1), Delta_(r)H_(2)"......." etc. for intermediate reactions ?
Answer» Solution :By Hess's law, `Delta_(r)H = Delta_(r)H_(1)+ Delta_(r) H_(2)+Delta_(r)H_(3)+"…......"`
