Question

N2 + 3H2 2NH3

Using the balanced equation above for the production of ammonia from nitrogen and hydrogen, how many moles of NH3 are produced when 1.7 moles of nitrogen reacts with hydrogen?

Answer 1

Answer:Considering the N2 only, 3 mols of N2 could form 6 moles of NH3. Considering the Hydrogen only, 8 moles of H2 could make 16/3 or 5 1/3 moles of NH3. 5 1/3 is less than 6, so the reaction is limited by the hydrogen, and 5 1/3 is the correct answer. Note that in reality this reaction does not go to completion, and this is just a textbook exercise.
