The Boltzmann Distribution

For reaction to take place, 3 things must happen –

  1. A collision must occur.
  2. Both particles must have enough energy.
  3. The particles must have the correct orientation.

The rate of reaction can be increased by –

  1. increasing the concentration/pressure, temperature and surface area as the number of collision increases.
  2. increasing the temperature as more particles have enough activation energy.
  3. 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.
