Question

What is the value of R?

(a) 18.4 mole/hr

(b) 44 mole/hr

(c) 70 mole/hr

(d) 98.5 mole/hr

I got this question in an international level competition.

My question is from Recycle with Chemical Reaction in division Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

Correct option is (c) 70 mole/hr

To explain I would say: 0.2 = – (-3.6)/(4 + 0.2*R), => R = 70 mole/hr.
