In a continuous flow stirred tank reactor, the composition of the exit stream_________________?
A Is same as that in the reactor
B Is different than that in the reactor
C Depends upon the flow rate of inlet stream
D None of these
Correct Answer: Is same as that in the reactor
Kinetics of a catalytic reaction can be best studied on a/an ______________ reactor?
A Mixed
B Integral (plug flow)
C Differential (flow)
D Either A., B. and C.
Correct Answer: Either A., B. and C.
Equilibrium of a chemical reaction as viewed by kinetics is a ______________ state?
A Dynamic steady
B Static steady
C Dynamic unsteady
D None of these
Correct Answer: Dynamic steady
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
Correct Answer: 7
In Langmuir treatment of adsorption,_________________?
A Whole surface of the catalyst does not have the same activity for adsorption and there is
B Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect
C All the adsorption does not take place by the same mechanism
D Extent of adsorption is more than one complete monomolecular layer on the surface
Correct Answer: Whole surface of the catalyst is essentially uniform and the adsorbed molecule has no effect
A non-catalytic chemical reaction of the type as shown in the bellow figure is called a _____________ reaction?
A Parallel
B Series
C Series-parallel
D None of these
Correct Answer: Series
A first order homogeneous reaction of the type X → Y → Z (consecutive reaction) is carried out in a CSTR. Which of the following curves respectively show the variation of the concentration of X, Y and Z with time ?
A I, II, III
B III, II, I
C III, I, II
D II, III, I
Correct Answer: III, II, I
Which of the following will give maximum gas conversion ?
A Fixed bed reactor
B Fluidised bed reactor
C Semi-fluidised bed reactor
D Plug-flow catalytic reactor
