Chemical Reaction Engineering
The gas phase reaction 2A ⇋ B is carried out in an isothermal plug flow reactor. The feed consists of 80 mole % A and 20 mole % inerts. If the conversion of A at the reactor exit is 50%, then CA/CA0 at the outlet of the reactor is

Chemical Reaction Engineering
For a heterogeneous catalytic reaction

The surface of the catalyst does not play an important role during reaction
Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction
A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important
The catalyst does not form an intermediate complex with the reactant
