WHAT FACTORS EFFECT THE RATE OF REACTION? The rate of reaction is the time taken for a reaction to complete, from beginning to end. The time is started when the chemicals are first added together. Key factors that effect the rate of reaction are: 1. Temperature 2. Concentration of chemicals 3. Surface area 4. The introduction of a catalyst 5. Pressure (When the reaction occurs between gasses only) Temperature: If the temperature of the reaction is increased, it speeds up the rate of reaction. This is because when heat is added, particles are given more energy. This makes them move faster and collide with more force. This means that collisions between particles are more likely, speeding up the rate of reaction. NORMAL TEMPERATURE INCREASED TEMPERATURE So, raising the temperature makes particles more often in a certain time, and makes it more likely that collisions result in a reaction. Because there are more effective collisions in the reaction,...
