Catalysts lower the activation energy of a reaction, allowing it to happen with less energy input
1 of 6
Reaction rate increases when tempreture increases
If particles mover faster, there is more chance of them bumping into eachother and therefore of a collision resulting in reaction
2 of 6
Pressure increased
Reacting particles get pushed closer together so there is more chance of a successful collision happening
3 of 6
Surface area increased
This means that there is a bigger area of a solid exposed, so there is a greater chance of collisions
4 of 6
Particles size gets smaller
Small particles have a greater overall area than the same amount of big particles. This means there are more particles exposed so more collisions happen
5 of 6
Reactants more concerntrated
If there are more reacting particles in a given volume, then there is a greater chance of them bumping into eachother.
