How does collision theory affect rate of reaction?
Answers
Temperature increases reaction rate because more collisions happen with more energy per collision. Pressure, Concentration and Surface Area affect rate of reaction because it increases the number of collisions. A catalyst lowers the activation energy barrier and so each collision has a higher % chance of happening
Collision theory states that the more number of collisions occur in a system, the more molecular bonds will be formed.
If we see according to the collision theory, the phenomena that can lead to collision in molecules are:
●Temprature
●Pressure
●Concentration
●Temprature : as temprature increases more bonds break in a system increasing their mobility and leading to collision.
●Pressure : when pressure is increased in a system the room for molecules to move is confined to a small space which increases the rate of collisions.
●Concentration : When there is greater number of molecules in a system there are greater chances of collision.
