Question 1 · 1 mark · Difficulty 1/3

In a closed container, nitrogen dioxide gas (NO₂) exists in equilibrium with dinitrogen tetroxide (N₂O₄). The equation is: 2NO₂(g) ⇌ N₂O₄(g). Which statement correctly describes a reversible reaction at equilibrium?

  1. The forward reaction has stopped completely
  2. The concentrations of reactants and products are equal
  3. The rate of the forward reaction equals the rate of the backward reaction
  4. Only the backward reaction is occurring
Show answer & explanation
✓ Answer: CThe rate of the forward reaction equals the rate of the backward reaction
Award 1 mark for stating that at equilibrium the rate of forward reaction equals the rate of backward reaction. A is incorrect — both reactions continue at equilibrium (dynamic equilibrium). B is incorrect — concentrations are constant but not necessarily equal. D is incorrect — both forward and backward reactions occur simultaneously.
Question 2 · 1 mark · Difficulty 1/3

A reversible reaction is one that can go:

  1. forwards and backwards
  2. forwards only
  3. backwards only
  4. neither way
Show answer & explanation
✓ Answer: Aforwards and backwards
A reversible reaction can proceed in both the forward and backward directions.

CXC CSEC Chemistry: Equilibria and Industrial Processes FAQ

How many CXC CSEC Chemistry questions on Equilibria and Industrial Processes are there on Kramizo?
Kramizo currently has 65 exam-board-aligned practice questions on Equilibria and Industrial Processes for CXC CSEC Chemistry, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Chemistry?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Equilibria and Industrial Processes practice with other Chemistry topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Equilibria and Industrial Processes questions aligned to the official CXC CSEC Chemistry syllabus?
Every question is written against the published CXC CSEC Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Equilibria and Industrial Processes typically tested on CXC CSEC Chemistry papers?
Equilibria and Industrial Processes appears across multiple question types on real CXC CSEC Chemistry papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
