Question

What is the single pass fraction conversion?

I got this question in a job interview.

My doubt stems from Recycle with Chemical Reaction topic in section Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

Right answer is (b) 20%

To elaborate: Single pass fraction conversion = (50 – 40)/50*100 = 20%.
