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 high pressure and eliminate inerts, when a > b Avoid recycle, when a > b Use batch reactor or plug flow reactor, when a > b Use CSTR with a high conversion, when a > b Use high pressure and eliminate inerts, when a > b Avoid recycle, when a > b Use batch reactor or plug flow reactor, when a > b Use CSTR with a high conversion, when a > b ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A batch adiabatic reactor at an initial temperature of 373°K is being used for the reaction, A → B. Assume the heat of reaction is - 1kJ/mole at 373°K and heat capacity of both A and B to be constant and equal to 50J/mole.K. The temperature rise after a conversion of 0.5 will be 10°C 100°C 20°C 5°C 10°C 100°C 20°C 5°C ANSWER DOWNLOAD EXAMIANS APP
