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 Increases Decreases Is at the highest allowable temperature throughout First increases and then decreases Increases Decreases Is at the highest allowable temperature throughout ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is 2 1 0 3 2 1 0 3 ANSWER DOWNLOAD EXAMIANS APP
