What is the Chemical Equilibrium Quiz?
The Chemical Equilibrium Quiz is a free, unofficial web app for practicing high school chemistry in a 4-choice quiz format.
The questions are original and cover equilibrium constants, reaction quotient, Le Chatelier-style predictions, gas equilibrium, weak acid equilibrium, and solubility equilibrium.
Original practice for equilibrium concepts
This app uses general chemistry facts, formulas, units, and self-made numerical settings. It does not reproduce textbook text, textbook exercises, entrance exam questions, mock exam questions, or worksheet problems.
The quiz focuses on short decisions: how to write K, how Q compares with K, which direction the equilibrium shifts, and how temperature, pressure, concentration, and catalysts affect equilibrium.
Course lineup
- 10-question chemical equilibrium basics
- 20-question equilibrium constant expressions
- 20-question concentration and reaction quotient
- 20-question Le Chatelier concentration changes
- 20-question temperature changes
- 20-question gas equilibrium and pressure
- 20-question weak acid equilibrium
- 30-question solubility equilibrium
- 50-question standard mixed practice
- 100-question full equilibrium review
Practice equilibrium, Le Chatelier's principle, and solubility step by step
The quiz helps students review equilibrium constants, Q and K, concentration and temperature changes, gas equilibrium, catalysts, weak acids, Ksp, common ion effects, and precipitation judgments.
Each question is short, but the hints show the reasoning path: write the expression, substitute values, compare Q and K, count gas coefficients, or decide which change offsets the stress.
Recommended ways to use this quiz
- Use the 10-question course when you want a quick check of chemical equilibrium basics.
- Use the 20-question courses to review a single topic such as K expressions, Le Chatelier shifts, gas equilibrium, weak acid equilibrium, or solubility equilibrium.
- Use the 50-question and 100-question courses for mixed review before tests or entrance-exam-style study.
- Use My Page to review frequently missed questions and repeat weak topics.
