Answer 1

Explanation:

Factors That Affect Reaction Rates. Factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of a catalyst.

Answer 2

Answer:

Heat.

light

catalyst

surface area

concentration of reactants

Explanation:

Surface area:If there is large surface area there is more chance of collsion course between them and the rate of reaction increases and vice versa.

Catalyst:Catalyst are those substances which alter the rate of chemical reaction.A certain amount of catalyst is required for a certain reaction.
