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 First increases and then decreases Decreases Increases Is at the highest allowable temperature throughout First increases and then decreases Decreases Increases Is at the highest allowable temperature throughout ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The reactions of high molecularity are rare, because Of very large activation energy of many bodies Many body collisions are not favoured energetically Of requirement of very large concentration for such reactions Of low probability of many body collisions Of very large activation energy of many bodies Many body collisions are not favoured energetically Of requirement of very large concentration for such reactions Of low probability of many body collisions ANSWER DOWNLOAD EXAMIANS APP
