A Maxwell–Boltzmann distribution shows the distribution of particle energies at a given temperature and allows for a qualitative estimation of the fraction of particles with sufficient energy to react at that temperature.

In a gas, there are lots of molecules traveling at lots of different speeds. Here's a framework for thinking about that. article https://www.khanacademy.org/science/ap-chemistry-beta/x2eef969c74e0d802:kinetics/x2eef969c74e0d802:activation-energy-and-reaction-rate/e/activation-energy-and-reaction-rate 2023-08-07T17:25:22.494770007Z Activation energy and reaction rate Check your understanding of activation energy and reaction rate in this set of free practice questions designed for AP Chemistry students. exercise
