Question

What is the value of C?

(a) 945.5 mole/hr

(b) 1874.6 mole/hr

(c) 2474.5 mole/hr

(d) 3951.2 mole/hr

I have been asked this question in a national level competition.

My doubt is from Recycle without Chemical Reaction in section Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

Right answer is (b) 1874.6 mole/hr

For explanation I would say: First reactor balance, KOH: 1000*0.5 + C*0.6 = B*0.8, => 4B = 3C + 2500, => B = 1874.6 mole/hr.
