Chemistry A level – Kinetics

*I apologise to my followers for spamming your feed with all these chemistry related posts! I’m throwing my notes away so I wanted to get these revision notes up onto the blog before I scrapped them. Bear with me please, I’ll post something that isn’t related to science soon!*

Increasing the temperature – this increases the rate of reaction because the particles have more kinetic energy therefore, they move faster, the frequency of collisions increase. More particles will have the minimum activation energy and therefore, it is most likely to have more successful collisions.

Increasing the pressure – this increases the rate of reaction because there are more particles in the same unit volume so, there are more collisions with the minimum activation energy and therefore, more successful collisions.

Increasing the concentration – increases the rate of reaction because there are more particles in the same unit volume so, there are more collisions with the minimum activation energy and therefore, more successful collisions.

Adding a catalyst – this increases the rate of reaction by providing an alternative pathway of lower minimum activation energy, so more particles have the minimum activation energy and therefore, there are more successful collisions.
