What does Activation energy mean |
A certain amount of energy needed for the reaction to take place. |
|
|
What is Collision Theory |
●Particles only react when they collide. ●Reactions that occur slowly have a lower rate of reaction. Whereas reactions that occur quickly have a high rate of reaction. ●As particles in the reaction get used up the reaction rate decreases. |
|
|
How does a Catalyst work? |
Catalyst work by providing an alternative route- involving an activation energy. |
|
|
What effects do Surface area have on a reaction? |
The larger the surface area the faster the rate of reaction as there is more area in contact with the other particles. |
|
|
What effects do Concentration have on a reaction? |
●If you increase the concentration of the reactants the reaction becomes faster.
●As this increases the number of times the particles collide per second |
|
|
What effects do Temperature have on a reaction? |
●The Higher the temperature the faster the Rate of Reaction. ●As the particles have more energy they are moving faster and hit each other more often ●As the particles have more energy when they collide they are more likely to have the activation energy. |
