1.	CH4 with pressure 10 atm and volume 5 liter at 27^oC is passed into a reactor with 50% excess oxygen, how many moles of oxygen is left in the products?(a) 2(b) 4(c) 6(d) 8The question was asked by my college professor while I was bunking the class.The origin of the question is Material Balances Involving Ideal Gases in division Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering
Answer» Correct answer is (a) 2 The BEST explanation: The reaction is CH4 + 2O2 -> CO2 + 2H2O, moles of CH4 = 105/(0.0821300) = 2, => moles of O2 left = 2*2(50/100) = 2.
