Question

What is the stoichiometric ratio of N2 to H2?

(a) 1:1

(b) 1:2

(c) 1:3

(d) 3:1

I have been asked this question in an online interview.

My doubt stems from Technical Manufacturing of Amino Compound topic in section Amination by Ammonolysis of Unit Processes

Answer 1

Correct answer is (c) 1:3

Best explanation: To obtain maximum conversion percentages at the selected operating pressures and temperatures, the law of mass action dictates that nitrogen and hydrogen be kept at the stoichiometric ratio of 1:3 and that gases which would cause lower partial pressures of the reactants should not be present.
