In the Contact Process, SO₃ is removed from the equilibrium mixture as it forms: 2SO₂(g) + O₂(g) ⇌ 2SO₃(g). What effect does removing SO₃ have?

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 Contact Process, SO₃ is removed from the equilibrium mixture as it forms: 2SO₂(g) + O₂(g) ⇌ 2SO₃(g). What effect does removing SO₃ have?

Accepted Answer

B: The equilibrium shifts right to replace the removed SO₃ — Removing a product decreases its concentration. By Le Chatelier's principle, the system responds by shifting right to replace the removed SO₃, increasing the overall yield. This is a key industrial strategy for improving conversion efficiency.

Answer

B: The equilibrium shifts right to replace the removed SO₃

Answer

D: The position of equilibrium is unchanged because a catalyst is present

Answer

C: The rate of the forward reaction decreases to compensate

Answer

A: The equilibrium shifts left to replace the removed SO₃
