WebAccording to the kinetic molecular theory, the average kinetic energy of gas particles is proportional to the absolute temperature of the gas. This can be expressed with the following equation where k represents the Boltzmann constant. The Boltzmann constant is simply the gas constant R divided by the Avogadro’s constant ( NA ). WebThe average translational kinetic energy for these molecules can be deduced from the Boltzmann distribution. When the Boltzmann distribution. is applied to the motion of a molecule in one dimension, it becomes. This distribution function can be used to calculate the average value of the square of the velocity.
WebThus the kinetic energy per Kelvin of one mole of (monatomic ideal gas) is 3 [R/2] = 3R/2. Thus the kinetic energy per Kelvin can be calculated easily: per mole: 12.47 J / K; per molecule: 20.7 yJ / K = 129 μeV / K; At standard … WebThe kinetic molecular theory is a simple but very effective model that effectively explains ideal gas behavior. The theory assumes that gases consist of widely separated molecules …
