For reaction to take place, 3 things must happen –
- A collision must occur.
- Both particles must have enough energy.
- The particles must have the correct orientation.
The rate of reaction can be increased by –
- increasing the concentration/pressure, temperature and surface area as the number of collision increases.
- increasing the temperature as more particles have enough activation energy.
- adding a catalyst as more particles have the correct orientation/the activation energy reduces.
The Boltzmann distribution is the distribution of energies of molecules at a particular temperature which can be often shown as graph.
By increasing the temperature, the number of molecules that have activation energy increases –
And by adding the catalyst, the activation energy reduces, therefore the number of particles that can react increases more greatly.
