Question

A gas mixture has 30% O2, 40% H2, and 30% N2 with molar volume of N2 10 L/mole at temperature 27^oC, what is the partial pressure of H2?

(a) 2.4 atm

(b) 3.6 atm

(c) 4.8 atm

(d) 6.4 atm

This question was addressed to me by my college professor while I was bunking the class.

Asked question is from Ideal Gas Mixtures and Partial Pressure in section Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer 1

The correct answer is (a) 2.4 atm

For explanation I would say: Molar volume of H2 = molar volume of N2 = 10 L/mole, PV = nRT, => P*10 = 0.0821*300, => P = 2.4 atm.
