[#276] A pulse tracer is introduced in an ideal CSTR (with a mean residence time ι) at time, t = 0. The time taken for the exit concentration of the tracer to reach half of its initial value will be
Correct Answer
(A) 2τ
[#277] An irreversible aqueous phase reaction, A + B → P, is carried out in an adiabatic mixed flow reactor. A feed containing 4 kmole/m 3 of each A and B enters the reactor at 8 m 3 /hr. If the temperature of the exit stream is never to exceed 390 K, what is the maximum inlet feed temperature allowed? (Data: Heat of reaction = -50 kJ/mole, Density of the reacting mixture = 1000 kg/m 3 , Specific heat of reacting mixture = 2 kJ/kg.K) The above data can be assumed to be independent of temperature and composition.
Correct Answer
(B) 290
[#278] A batch reactor is suitable for
Correct Answer
(C) Liquid phase reactions
