CHEMICAL REACTION
COLLISION THEORY
CONCENTRATION
TEMPERATURE
SURFACE AREA
CATALYST
States that the rate of a chemical reaction is proportional to the number of collisions between the reactant particles.
CHEMICAL REACTION

TEMPERATURE
SURFACE AREA
CATALYST
CHEMICAL REACTION
If the temperature of reactants is increased, the kinetic energy that it possesses also increases resulting to more collisions among the particles.
