In the Haber process, only about 15% of the nitrogen and hydrogen reacts on each pass through the reactor. How does the industry address this low conversion?

Q: How do I try a free CIE Chemistry question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Chemistry bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Chemistry students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Chemistry questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Chemistry syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

In the Haber process, only about 15% of the nitrogen and hydrogen reacts on each pass through the reactor. How does the industry address this low conversion?

Accepted Answer

C: By recycling the unreacted gases back through the reactor — Unreacted nitrogen and hydrogen are recycled back into the reactor so they can react again, improving the overall efficiency of the process. Changing the temperature or pressure beyond chosen conditions would compromise the balance between rate and yield.

Answer

D: By increasing the pressure above 1000 atm to maximise yield

Answer

C: By recycling the unreacted gases back through the reactor

Answer

A: By using a more reactive catalyst to increase conversion to 100%

Answer

B: By raising the temperature to shift equilibrium further towards ammonia
