WebMaxwell Boltzmann distribution. The key characteristics are; 1. No particles have zero energy 2. Most particles have intermediate energies 3. A few particles have very high energies indeed 4. The average energy is not the same as the most probable energy 1. The sketch opposite shows a typical Maxwell Boltzmann distribution. WebWe can use the Boltzmann distribution to help us explain why rate increases with temperature. We need to mark the Activation Energy, E A, for the reaction on the energy (x-) axis. We can then state that the area under the Boltzmann distribution curve and above E A at a lower temperature (which is the same as the number of particles with energy ... WebThe Maxwell–Boltzmann distribution ( Figure 3) can be used to describe the fraction of molecules with different kinetic energies in a population of molecules at a specified temperature, and allows the estimation of the fraction of the molecules in a population that exceed the activation energy of a reaction. nicole scherzinger net worth 2016
