Factors that effect kinetics(rate of reactions)

Concentration of reaction

Increasing the concentration of a reactant molecule leads to a faster reaction rate, as more reactant molecules are colliding with each other increasing the frequency of efficient collisions.

Temperature

Increasing the temperature increases the rate of reaction as higher temperature provides more energy to the reactant molecules, leading the greater kinetic energy and more frequent collision.

Catalysts

They remain unchanged at the end of the reaction and significantly increase the reaction rate.

Surface area

Increasing surface area increases the rate of reaction for solid reactants as it provides opportunities for collision between reactant molecules.

Presence of light

Some reactants are affected by the presence of light as light provides the necessary energy to initiate reactants

Pressure

For the gas- phase the increase in pressure increases the reaction rates by increasing the frequency of collision between gas molecules. (this is esp true for involving gas as reactants)

Nature of reactants

Specific chemical properties and structures of reactants can influence reaction rates. Eg. Reactants that have higher reactive molecules may proceed more quickly than reactions involving less reactive molecules.
