A plug flow reactor followed by CSTR

CSTR followed by a plug flow reactor

keff = k + kg

keff = (k+ kg)/2

keff = (kkg)1/2

1/keff = 1/k + 1/kg

Increases

Decreases

Remains unaffected

Unpredictable from the data

Size requirement

Distribution of reaction products

Both A and B

Neither A nor B

Is same as that in the reactor

Is different than that in the reactor

Depends upon the flow rate of inlet stream

None of these
