Factors affecting reaction

how to speed up a reaction

1 - Increasing the number of collisions per second

2 - Increasing the amount of energy particles have

Agitation

mixing or stirring speeds up reaction rate exposing unreacted particles

sometimes product particles build up on the reactants like bubbles and block the reactant particles from collision

agitation can remove this build up

State of subdivision (surface area)

breaking up reactant chemicals into smaller pieces means greater surface area is exposed to reaction

if more reactant particles are exposed, there will be more particle collisions per second

Concentration

as concentration increases, there are more particles in given volume

this results in more particles per second, increasing reaction rate

Temperature rate

Influences both factors of collision theory

particles at higher temp have higher kinetic energy, therefore particles collide more
