The residence time distribution of an ideal CSTR is

To maximise the formation of R in the simultaneous reactionA + B → R , rR = 2CA0.5.CB2 A + B → S , rS = 1.5 CA.CB We should have

The rate constant of a reaction depends on the

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 $$\frac{{{{\text{C}}_{\text{A}}}}}{{{{\text{C}}_{{{\text{A}}_{\text{0}}}}}}}$$ at the outlet of the reactor is

The molecularity and the order of reaction respectively, for the hydrolysis of methyl acetate in presence of acids are
