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
The catalyst does not form an intermediate complex with the reactant
A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important

Chemical Reaction Engineering
Pick the WRONG design guideline for a reactor in which the reactions, A → R (desired) and A → S (undesired) are to take place. The ratio of the reaction rates is rR/rS = (k₁/k₂).Csub>Aa-b

Use CSTR with a high conversion, when a > b
Use batch reactor or plug flow reactor, when a > b
Use high pressure and eliminate inerts, when a > b
Avoid recycle, when a > b
