Factors that affect rate of reaction

factors which affect rate of reaction

o concentration

o pressure

o surface area

o temperature

o catalysts

How does concentration affect the rate of reaction

-A higher concentration means there are more reactant particles per unit volume,

-so a higher chance of the particles colliding,

-meaning there are more successful collisions so a higher rate of reaction

How does pressure affect the rate of reaction

-Increasing the pressure of a gas reaction can increase the rate of reaction,

-as it forces the gas particles to occupy a smaller volume,

-leading to more frequent collisions between the particles.

How does surface area affect the rate of reaction

-increasing the surface area of the reactants will increase the number of available sites for collision.

-This results in more successful collisions between reactant particles and a faster rate of reaction.

How does temperature affect the rate of reaction

-Temperature affects the rate of a reaction because increasing the temperature will increase the kinetic energy of the reactant particles.

-This results in more successful collisions between reactant particles and a faster rate of reaction.

How does a catalyst affect the rate of reaction

-A catalyst affects the rate of a reaction by lowering the activation energy required for the reaction to occur.

-This means that fewer collisions between reactant particles are needed to reach the energy threshold required for the reaction to occur, resulting in a faster rate of reaction.
