Question

The flow in rate of A and B are 8 mole/s and 10 mole/s respectively, which under goes reaction 4A + 5B -> 3C, what is the flow out rate of C?

(a) 4 mole/s

(b) 6 mole/s

(c) 8 mole/s

(d) 10 mole/s

This question was addressed to me during an internship interview.

My enquiry is from Open and Closed Systems topic in division Introduction to Material Balances of Basic Chemical Engineering

Answer 1

The correct option is (b) 6 mole/s

To explain: Flow out rate of C = 3*2 = 6 mole/s.
