Most probable speed in Maxwell—Boltzmann statistics

The most probable speed is the speed at which the Maxwell—Boltzmann speed distribution function is maximum.

Notation:

  1. \(k_\text{B}\) (k_B) is boltzmann_constant.

Conditions:

  1. The gas is in thermal equilibrium with the environment.

  2. The gas particles are distributed according to Maxwell—Boltzmann statistics.
