Rates of Reaction
1 Catalysts
1.1 lower the activation energy
1.2 give an alternative pathway for a reaction to occur
1.3 they don't change chemically during the reaction
1.3.1 so they can be used again
2 Surface Area
2.1 a bigger surface area will increase the rate of reaction
2.1.1 as there is a bigger area, there is a higher chance of a collision between particles with the correct orientation
3 Temperature
3.1 high temperature
3.1.1 increases the rate of reaction
3.1.2 makes particles collide more often in a certain time
3.1.3 makes it more likely that collisions will result in a reaction
4 Concerntration
4.1 high concerntration
4.1.1 increases the chance of a collision
4.1.1.1 with the correct orientation for a reaction
5 Collision Theory
5.1 a reaction will only occur between two particles if...
5.1.1 they have the correct collision orientation
5.1.2 they have the right activation energy (Ea)
