Question

CO with pressure 10 atm at 27^oC is passed through a reactor with O2, what is the pressure of CO2 produced if 60% CO reacted?

(a) 2 atm

(b) 6 atm

(c) 10 atm

(d) 14 atm

I have been asked this question during a job interview.

My question comes from Material Balances Involving Ideal Gases topic in division Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

The correct option is (b) 6 atm

To explain I would say: The reaction is 2CO + O2 -> 2CO2, pressure of CO2 = 10*0.6 = 6 atm.
