A feed stream containing 2.00 mol/min butane and a feed stream containing 130 mol/min of air are fed into a reactor. The butane combusts completely according to the following reaction:
2C4H10 + 13O2 ---> 8CO2 + 10H2O
Assume that the air is 21 mol% O2 and 79 mol% N2
Set up equations and find:
q1 mol CO2/min
q2 mol H2O/min
q3 mol N2/min
q4 mol O2/min
