How can we change the rate of a chemical reaction?
Add another ingredient. For example is you have a grease fire on the top of your stove, add a gallon of water and observe the chemical reaction properties of another ingredient.
Poly more of the reactant.
Add an accelerator.
By its concentration,temperature, pressure and by using catalysts.
a catalys (i dont think i spelld it right) can speed up a reaction i think vinegar some oher chemical and steel wool get really ot and speed up rusting
