The fractional yield of C with respect to A for the reaction A \(^{\underrightarrow{C}}\) cC + rR is the ratio of ____(a) All R formed to all A reacted(b) All A reacted to all R formed(c) All A reacted to all C formed(d) All C formed to all A reactedI had been asked this question in an online quiz.My question is from Microbial Fermentation in chapter Bioreactors, Enzyme and Microbial Fermentation of Chemical Reaction Engineering |
|
Answer» Correct CHOICE is (d) All C formed to all A REACTED |

The value of τm,washout given N = 4 and k=1 is____(a) 1.06(b) 1.34(c) 2.45(d) 3.86This question was addressed to me during an online exam.I'd like to ask this question from Microbial Fermentation topic in portion Bioreactors, Enzyme and Microbial Fermentation of Chemical Reaction Engineering |
|
Answer» CORRECT option is (a) 1.06 Best EXPLANATION: τm,washout = \(\frac{N^2}{(N^2-1)K} = \frac{16}{15}\) = 1.06 |

| 3. |
With an accumulation of waste formed during the reaction, the value of observed Monod rate constant ____(a) Decreases(b) Increases(c) Remains constant(d) First decreases and then increasesThis question was posed to me during a job interview.This is a very interesting question from Microbial Fermentation topic in division Bioreactors, Enzyme and Microbial Fermentation of Chemical Reaction Engineering |
|
Answer» CORRECT OPTION is (a) Decreases To elaborate: The ACCUMULATION of WASTE formed decelerates the reaction rate. This decrease is reflected in the reaction rate constant. |

The value of CR,opt for product limiting microbial fermentation (in kg/m^3), given the value ofCR*=60 kg/m^3 is ____(a) 30(b) 20(c) 15(d) 10This question was addressed to me in unit test.Enquiry is from Microbial Fermentation in section Bioreactors, Enzyme and Microbial Fermentation of Chemical Reaction Engineering |
|
Answer» RIGHT CHOICE is (a) 30 The explanation: CR,opt = \(\FRAC{C_R*}{2} = \frac{60}{2}\) = 30 kg/m^3. |
|
| 5. |
If CA0 = 8 and CM = 1, the value of N is ____(a) 4(b) 1(c) 2(d) 3I had been asked this question in unit test.I'm obligated to ask this question of Microbial Fermentation topic in chapter Bioreactors, Enzyme and Microbial Fermentation of Chemical Reaction Engineering |
|
Answer» CORRECT CHOICE is (d) 3 The BEST I can explain: N = (1+\(\frac{C_{A0}}{C_M}\))^0.5 = (1+\(\frac{8}{1}\))^0.5 = 3. |
