- In case of a __________ reactor, the composition in the reactor and at the exit of the reactor is the same.
- For reactions in parallel viz A → P (desired product) and A → Q (unwanted product), if the order of the desired reaction is higher than that of the undesired reaction, a
- Maximum equilibrium conversion for endothermic reaction is obtained at the __________ temperature.
- The gas phase reaction 2A ⇋ B is carried out in an isothermal plug flow reactor. The feed consists of 80 mole % A and 20 mole % inerts. If the conversion of A at the reactor exit is 50%, then CA/CA0 at the outlet of the reactor is

A.
Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction |
|
B.
A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important |
|
C.
The catalyst does not form an intermediate complex with the reactant |
|
D.
The surface of the catalyst does not play an important role during reaction |
