1.	A gas mixture with 50% H2 at the rate F is passed through a reactor and it produced a gas mixture with 80% H2 at the rate 15 liter/s, what is the value of F?(a) 5 liter/s(b) 8 liter/s(c) 15 liter/s(d) 24 liter/sThis question was posed to me in an interview for internship.Question is taken from Material Balances Involving Ideal Gases in division Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering
Answer» RIGHT answer is (d) 24 liter/s Best explanation: OVERALL H2 balance: 0.5F = 0.8*15, => F = 24 liter/s.
