250+ TOP MCQs on Choosing of Right Reactor Series or Connections (Maximum Profitability) and Answers

Chemical Reaction Engineering MCQs on “Choosing of Right Reactor Series or Connections (Maximum Profitability)”.

1. How should the two MFR’s of unequal size be connected in series to maximize production for a first order homogenous reaction?
a) Smaller MFR followed by larger MFR
b) Larger MFR followed by smaller MFR
c) Any arrangement
d) MFR’s should not be connected in series
Answer: c
Clarification: The final concentration for both the cases is same and can be calculated using the formula
C_A2 = (frac{CA0}{(τ1K+1)(τ2k+1)} )
Hence, it can be inferred that for first order reactions, irrespective of the arrangements the final conversions are going to be the same.

2. For all positive reaction orders and any particular duty the MFR is always larger than the PFR.
a) True
b) False
Answer: a
Clarification: Comparison of performance of single MFR and PFR are made for the nth order and was inferred that the MFR is always larger than a PFR for a given duty.

3. How should a PFR and MFR be connected to maximize production from a first order reaction?
a) MFR followed by PFR
b) PFR followed by MFR
c) Any arrangement
d) MFR and PFR should not be connected
Answer: c
Clarification: The final concentration for both the cases is same and can be calculated using the formula
C_A2 = (frac{CA0 e^{-kτp}}{(τmk+1)} )
Therefore, any arrangement does not make any difference for first order reactions.

4. Graphical procedure for finding conversion in MFR’s of different sizes in series is called ______ method.
a) Newton’s
b) Wheeler’s
c) Octaves
d) Jones
Answer: d
Clarification: A graphical procedure was presented by Jones in 1951 to estimate the outlet composition of MFR’s in series.

5. Best arrangement of reactors for a reaction whose rate-concentration curve that rises monotonically.
a) Plug, Large MFR, Small MFR
b) Plug, Small MFR, Large MFR
c) Large MFR, Small MFR, Plug
d) Small MFR, Plug, Large MFR
Answer: b
Clarification: For this kind of rate-concentration curve, the concentration should be kept as high as possible, therefore this arrangement should be used.

6. Determine the space time of a PFR for the given reaction-concentration curve where the concentration is to be reduced from 1.6 to 0.4 mol/lit in minutes.

a) 5
b) 9
c) 19
d) 32
Answer: c
Clarification: The basic design equation for a PFR is
τ = (int_{CA0}^{CAf}frac{-dCA}{-rA} )
Therefore, the area under the curve in a 1/-r_A vs C_A gives the space time.

7. Find the size of the MFR in litres required to achieve 40% conversion for a flowrate of 100 lit/min.

a) 10.68
b) 15.83
c) 3.45
d) 7.65
Answer: d
Clarification: The basic design equation for a MFR is
(frac{τ}{CA0} = frac{XA}{-rA} )
A rectangle is to be drawn as shown in the fig below. And the area of the rectangle gives the space time.

τ = (frac{V}{v0} )

From graph space time was found to be 0.0765 minutes.
So V = 0.0765*100 = 7.65 lit.

8. Four MFR’s are operated in series the total space time is 5 minutes. If it is replaced by a single PFR, What will be the space time? First order reaction with rate constant 2 min^-1, concentration reduces from 50 to 10 mol/m³.
a) 0.805
b) 0.123
c) 0562
d) 0.439
Answer: a
Clarification: The design equation of PFR is τ = (int_{CA0}^{CAf}frac{-dCA}{-rA} )
For the 1^st order reaction the equation is simplified as kτ = -ln⁡((frac{CA}{CA0}))
τ = -0.5ln⁡((frac{10}{50})) = 0.805 minutes.

9. Effect of flow type on reactor performance when the conversion is small.
a) no effect
b) cannot be determined
c) very small
d) very large
Answer: c
Clarification: The reactor performance is not affected by flow type when the conversion is small. If the conversion is very high, flow type largely affects the reactor performance.

10. The concentration profile shown is for __________

a) MFR in series
b) MFR
c) PFR in series
d) PFR
Answer: a
Clarification: The concentration profile is for MFR’s in series. The entire series can be replaced by a PFR whose volume is smaller than the total volume of the MFR’s.

56. In a MapReduce job, the reducer receives all values associated with same key. Which statement best describes the ordering of these values?

A. The values are in sorted order.

B. The values are arbitrarily ordered, and the ordering may vary from run to run of the same MapReduce job.

C. The values are arbitrary ordered, but multiple runs of the same MapReduce job will always have the same ordering.

D. Since the values come from mapper outputs, the reducers will receive contiguous sections of sorted values.

Answer: B

57. You need to create a job that does frequency analysis on input data. You will do this by writing a Mapper that uses TextInputFormat and splits each value (a line of text from an input file) into individual characters. For each one of these characters, you will emit the character as a key and an InputWritable as the value. As this will produce proportionally more intermediate data than input data, which two resources should you expect to be bottlenecks?

A. Processor and network I/O

B. Disk I/O and network I/O

C. Processor and RAM

D. Processor and disk I/O

Answer: B

58. You want to count the number of occurrences for each unique word in the supplied input data.

You’ve decided to implement this by having your mapper tokenize each word and emit a literal value 1, and then have your reducer increment a counter for each literal 1 it receives. After successful implementing this, it occurs to you that you could optimize this by specifying a combiner. Will you be able to reuse your existing Reduces as your combiner in this case and why or why not?

A. Yes, because the sum operation is both associative and commutative and the input and output types to the reduce method match.

B. No, because the sum operation in the reducer is incompatible with the operation of a Combiner.

C. No, because the Reducer and Combiner are separate interfaces.

D. No, because the Combiner is incompatible with a mapper which doesn’t use the same data type for both the key and value.

E. Yes, because Java is a polymorphic object-oriented language and thus reducer code can be reused as a combiner.
