Reaction rate

How quickly or slowly reactants are turned into products is called the reaction rate

Temperature

Increasing temperature will INCREASEthe rate of a chemical reaction.

Explanation:

Increasing temperature increases the molecular movement of the reactants.

Therefore, reactants collide more often and produce products at a faster rate.

Surface area

Increasing the surface area of the reactants will INCREASE the rate of a chemical reaction.

Explanation:

Powders will react faster than solid blocks because there is more surface area for reactants to collide.

Concentration

Increasing the concentration of the reactants will INCREASE the amount of product formed in a chemical reaction.

Explanation:

Increasing concentration of reactants means more reactants to produce more products

Catalysts

Adding a catalyst to a chemical reaction will INCREASE the rate of a chemical reaction.

Explanation:

Catalysts speed up chemical reaction but are not used in the reaction.

Example = enzymes

Enzymes

Enzymes are catalysts that are found in living organisms.

These speed up chemical reactions without being used up in the reaction.

Example: digestive enzymes
