There are 4 main factors that affect the rate of a chemical reaction:
1. Concentration of reactants, if you have more reactants, the reaction must produce more products in order to reach equilibrium
2. Surface area, the bigger the surface area, the more collisions can occur and therefore the reaction will occur in a higher rate
3. Temperature, if you increase the temperature this means an increase of kinetic energy, which is movement, therefore with more movement, more collisions and more reaction occurring
4. Catalyst, this is a substance that the main function is to lower the energy of activation of a reaction, therefore it will increase the rate of the reaction
