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

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