A pollutant P degrades according to first order kinetics. An aqueous
stream containing P at 2 kmole/m3 and volumetric flow rate 1m3
/h requires
a mixed flow reactor of volume V to bring down the pollutant level to 0.5
kmole/m3
. The inlet concentration of the pollutant is now doubled and the
volumetric flow rate is tripled. If the pollutant level is to be brought down to
the same level of 0.5 k.mole/m3
, the volume of the mixed flow reactor should
be increased by a factor of:
(A) 7
(B) 6
(C) 3
(D) 7/3
