The catalyst does not form an intermediate complex with the reactant

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

None of these

Moles formed/volume of reactor) (time)

Mole formed/volume of catalyst) (time)

Moles for med/(surface of catalyst) (time)

Suitable for gas phase reactions

Ideal at very low conversion

Same as ideal stirred tank reactor

Same as plug flow reactor (PFR)
