Different types of chemical reactions are used to produce a range of products and can occur at different rates

This online resource demonstrates the collision theory of chemical reactions.

The resource is a web-based java application that allows students to model the effects of temperature on the rate of collisions in a closed system to see how this affects chemical reaction rates.

Users can alter the number of particles in their model and change the temperature of the reaction, and by observing the simulation they can see how the number of collisions are affected.

See the Additional Information section about how to access the resource.

This online resource details the chemistry involved in the extraction of metal from ore.

The resource is a set of web pages concerning the chemical reactions and processes commonly used in the mining industry.

The reaction types covered include oxidation and reduction reactions as well as electrolysis for extracting more reactive metals.

The web page also has an interactive multiple choice test to check learning.

These tests give instant feedback and comments if students choose an incorrect answer.
