N2 with pressure 10 atm and H2 with pressure 30 atm, both with volume

1.	N2 with pressure 10 atm and H2 with pressure 30 atm, both with volume 10 liter at 27^oC are passed into a reactor, how many moles NH3 is produced?(a) 4(b) 8(c) 12(d) 16I had been asked this question during an interview for a job.The query is from Material Balances Involving Ideal Gases topic in division Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering
Answer» Correct choice is (b) 8 For explanation: The reaction is N2 + 3H2 -> 2NH3, MOLES of N2 = 1010/(0.0821300) = 4, moles of H2 = 3010/(0.0821300) = 12, => extent of reaction = (0 – 4)/(-1) = 4, => moles of NH3 = 4*2 = 8.
