factors that affect the rate of a reaction :





surface area ↳
pressure
↳ concentration of reactants ↳ catalysts ( enzymes )


temperature where the chemical reaction occurs .

for products formed the collision must have certain minimum amount of
energy activation

catalyst :




-



speeds up a chemical reaction without being and isn't changed by the reaction

, reaction rate :



↳ of the reaction
the measure of how
quickly the reactants in a reaction change into the
product
-

how to measure reaction rate :




↳ how decrease
quickly reactants




[
↳ how
quickly the
product increase
