Answer» Right option is (a) ε = (frac{Change , in , number , of , moles , of , the , reaction , system , when , the , reaction , is , complete}{Total , number , of , moles , fed} ) To elaborate: ε is the fractional change in volume of the reaction system between no conversion and complete conversion of the reactant. It is the ratio of the change in moles of the reaction mixture to achieve complete conversion to the number of moles fed initially. |
