Chemguide: Core Chemistry 14 - 16


Rates of Reaction Menu


These pages tend to build on each other and it would be best to read them in this order.

The effect of surface area on reaction rates . . .

A commonly used experiment to investigate this, and an explanation of why surface area affects the rates of reactions involving a solid and a liquid or gas.

The effect of concentration on reaction rates . . .

Another commonly used experiment to investigate this, and an explanation of why concentration matters.

The effect of temperature on reaction rates . . .

An explanation of why temperature affects rates of reaction. I am using the same experiment to demonstrate this as in the concentration page. It would be helpful if you read that page first.

The effect of pressure on reaction rates . . .

The effect of increasing the pressure on reactions involving gases.

The effect of catalysts on reaction rates . . .

Explaining why catalysts affect reaction rates. The common example of using manganese(IV) oxide in the decomposition of hydrogen peroxide.
