Resource summary
Rate of Reaction Factors Mind Map
Temperature
Increasing the temperature increases the rate of reaction
Particles have more energy, so move faster and are more likely to collide
Higher collision frequency means a higher rate of reaction
Concentration
Increasing concentration increases the rate of reaction
More reactants in reaction vessel means successful collisions are more likely
Pressure
Changes in pressure have no effect on reactions that involve solids and liquids
Increasing pressure increases the rate of reaction for reactions involving gases
Reactant particles are squeezed closer together so collision frequency increases
Catalysts
Substances that change the rate of reaction but remain chemically unchanged at the end of the reaction
Catalysts provide a surface on which the reacting molecules can collide
Reduces the amount of energy required for a successful collision
Many particles will have more energy than this lower threshold, and so the collision frequency and rate of reaction will increase
Surface area
Increasing the surface area to volume ratio of the reactants increases the rate of reaction
When one of the reactants is in a large lump, the other reactant cannot react with the particles in the middle
Smaller particle size leads to higher surface are and an increase in the collision frequency
