Question

The flow in rate of CH4 and O2 in a system are 2 mole/hr each what is the flow out rate of CO2?

(a) 1 mole/hr

(b) 2 mole/hr

(c) 3 mole/hr

(d) 4 mole/hr

This question was addressed to me in class test.

My question comes from Accounting for Chemical Reactions in Material Balances in portion Introduction to Material Balances of Basic Chemical Engineering

Answer 1

The correct choice is (a) 1 mole/hr

To explain: The reaction is CH4 + 2O2 -> CO2 + 2H2O, => flow out rate of CO2 = 1*1 = 1 mole/hr.
