Rates of Reaction
Changing the Rate of a Reaction.
There are 5 ways to
increase the rate of a chemical
They are all understood in terms of collision theory.
The rate of a chemical reaction may be increased by
1) Raising the temperature.
2) Increasing the concentration (in solution).
3) Increasing the pressure (in gases).
4) Increasing the surface area of a solid.
5) Use a catalyst.
The opposite of 1, 2, 3 and 4 will decrease the rate of a reaction.
A catalyst (strictly speaking) will change the rate of a reaction.
A catalyst can make a reaction go faster or slower.
In practice a catalyst is mainly used to make a reaction go faster.
