Chemistry Question Harber Process

Question

If you have 0.75 moles of hydrogen gas and excess nitrogen gas hoe many moles of ammonia will be produce?

Answer 1

First write a balanced equation for the Haber Process:

N₂ + 3H₂ = 2NH₃

1 mol: 3 mol = 2 mol

You have 0.75 moles of hydrogen and the molar ratio of 3H_2:2NH₃ = 3:2

So 3:2 ratio = 0.75 moles H2 : (0.75 /3)*2 Moles NH₃

0.75 moles H2 : 0.50 moles NH3.

So this will produce 0.50 moles of NH3
