Question

The flow in rate of HCl and NaOH in a system are 1 mole/hr each what is the flow out rate of NaCl?

(a) 1 mole/hr

(b) 2 mole/hr

(c) 3 mole/hr

(d) 4 mole/hr

This question was posed to me in an internship interview.

I'd like to ask this question from Accounting for Chemical Reactions in Material Balances topic in division Introduction to Material Balances of Basic Chemical Engineering

Answer 1

Correct option is (a) 1 mole/hr

For explanation: The reaction is HCl + NaOH -> NaCl + H2O, => flow out rate of NaCl = 1 mole/hr.
