Factors affecting Rates of Reaction

What are the 4 factors that affect the rate of reaction?

1. Concentration

2. Surface area

3. Temperature

4. Use of catalysts

How does concentration affect the rate of reaction?

1. Increasing the concentration will increase the rate of reaction.

2. This is because increasing the number of reacting particles will lead to more frequent and successful collisions, thus, increasing the rate of reaction.

How does surface area affect the rate of reaction?

1. Increasing the surface area will increase the rate of reaction.

2. This is because the reacting particles will have a greater surface area to react over, allowing for more frequent and successful to occur, thus, increasing the rate of reaction.

How does temperature affect the rate of reaction?

1. Increasing the temperature will increase the rate of reaction.

2. This is because the reacting particles will have more kinetic energy for greater movement. As these particles move more quickly, they will collide more frequently and successfully, thus, increasing the rate of reaction.

How do catalysts affect the rate of reaction?

1. Catalysts provide the reaction with an alternate pathway that requires less activation energy, without being used up in the process.
