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

Chemical Reaction Engineering If helium is introduced in a reactor containing O₂, SO₂ and SO₃ at equilibrium, so that total pressure increases while volume and temperature remains constant. In this case the dissociation of SO₃ (as per Le Chatlier principle) Increases Decreases Remains unaltered Changes unpredictably Increases Decreases Remains unaltered Changes unpredictably ANSWER DOWNLOAD EXAMIANS APP
