Ideal Gas Equation Problem 4

Question

Consider the equation: 4 NH₃(g) + 5 O₂(g)= 4 NO(g) + 6 H₂O(g)

At a constant temperature and pressure, what is the maximum volume, in liters, of NO that can be made from 3.0 L or NH₃ and 3.0 L of O₂?

Answer 1

O₂ will be limiting. You can tell this by dividing the liters of each by thei coefficient in tge balanced equation.

For NH3 you have 3.0 L/4 = 0.75

For O₂ you have 3.0 L/5 = 0.6

0.6 < 0.75 so O2 is limiting.

Max volume of NO = 3.0 L O2 x 4 L NO/5 L O2 = answer
