Chemical Reaction Engineering A reversible liquid phase endothermic reaction is to be carried out in a plug flow reactor. For minimum reactor volume, it should be operated such that the temperature along the length Increases Is at the highest allowable temperature throughout Decreases First increases and then decreases Increases Is at the highest allowable temperature throughout Decreases First increases and then decreases ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For identical flow rate and feed composition, X plug flow reactors (PER) in series with a total volume V gives the same conversion as single CSTR of volume V PFR of volume V/X CSTR of volume V/X PFR of volume V CSTR of volume V PFR of volume V/X CSTR of volume V/X PFR of volume V ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Rate constant 'k' and absolute temperature 'T' are related by collision theory (for bimolecular) as k ∝ T1.5 k ∝ T k ∝ exp(-E/RT) k ∝ √T k ∝ T1.5 k ∝ T k ∝ exp(-E/RT) k ∝ √T ANSWER DOWNLOAD EXAMIANS APP
