What are 4 ways to speed up the rate of a chemical reaction

1. Use a catalyst.

A catalyst is a substance that can alter the rate of a chemical reaction.

2. Increase the temperature.

For most chemical reactions, temperature is directly proportional to the rate of a chemical reaction.

3. Concentrate on the reactants.

The concentration of the reactants also plays an important role in determining the rate of a chemical reaction.

And finally the fourth way.

4. Increase the surface area of the reactants.

Increasing the surface area of the reactants increases the rate of the reaction.
