The Maxwell-Boltzmann Distribution describes the distribution of speeds among particles in a gas. It shows how many particles have a certain speed at a given temperature, indicating that most particles move at moderate speeds, while fewer particles move very slowly or very quickly. This distribution is crucial for understanding the behavior of gases in thermodynamics. This concept is named after James Clerk Maxwell and Ludwig Boltzmann, who developed the theory in the 19th century. The distribution helps explain various phenomena, such as diffusion and reaction rates, by illustrating how temperature affects particle motion and energy.
