Increasing the temperature causes faster collisions
At a higher temperature there will be more particles colliding with enough energy to make the reaction happen.
1 of 5
Catalysts speed up reactions
A solid catalyst works by giving the reacting particles a surface to stick to.
2 of 5
Catalysts help reduce costs in industrial reactions
They increase the rate of reaction, which saves a lot of money and it will allow the reaction to work at a much lower temperature.
3 of 5
There are disadvantages to using catalysts
They can be very expensive to buy and often need to be removed from the product and cleaned.
4 of 5
You only need a minimum amount of energy by the particles to react
This is known as the activation energy
