4 factors that can affect the rate of a reaction:-temperature


-particle size 


for a reaction to occur, particles must collide and combine to form new products.

temperature:-the higher the temperature, the faster the reaction 

                     - the lower the temperature, the slower the reaction

increasing temperature, increases the energy of the particles making them move faster and so more successful collisions can
