Rates and Equilibrium

Simple explanation

Rate measures how quickly reactants are used or products are made.

Analogy or example

Powdered calcium carbonate reacts faster than marble chips because it has a larger surface area.

Misconception trap

Catalysts increase the amount of product made.

Real-world relevance

Rates of reaction links classroom reactions to materials, energy, resources and everyday products.

Simple explanation

A reversible reaction can go in both directions.

Analogy or example

Increasing pressure favours the side with fewer gas molecules.

Misconception trap

Equilibrium means the reaction has stopped.

Real-world relevance

Reversible reactions links classroom reactions to materials, energy, resources and everyday products.

Simple explanation

Collision theory sits inside Rates and Equilibrium, so learn the core definition and the exam example that usually comes with it.

Analogy or example

For a longer answer, start with particles or bonding, then connect that to the observation or calculation.

Misconception trap

Collision theory can be confused with nearby Rates and Equilibrium ideas.

Real-world relevance

Collision theory links classroom reactions to materials, energy, resources and everyday products.
