6. Rate and extent of chemical change

Factors affecting rates of reaction

Loading...

Description

Having learnt how to measure rates of reaction and interpret rate graphs, we now discuss the five main factors that affect the rate of a reaction: temperature, concentration, pressure, surface area and catalysts. In the second half of the video, we also look at the requirements for the required practical on this topic: investigating how changes in concentration affect the rates of reactions, with specific reference to a method involving a change in colour.

Key Words

concentration, rate of reaction, gradient, rate, temperature, pressure, surface area, catalyst, required practical, thiosulfate
