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 If n = overall order of a chemical reaction. a = initial concentration of reactant. t = time required to complete a definite fraction of the reaction. Then pick out the correct relationship. T ∝ 1/an T ∝ 1/an - 1 T ∝ an T ∝ 1/an + 1 T ∝ 1/an T ∝ 1/an - 1 T ∝ an T ∝ 1/an + 1 ANSWER DOWNLOAD EXAMIANS APP
