Video answer: Translational partition function
Top best answers to the question «Translational partition function for monatomic gas»
18.1: The Translational Partition Function of a Monatomic Ideal Gas. which is the product of translational partition functions in the three dimensions. We postulate therefore that the observed energy of a macroscopic system should equal the statistical average over the partition function as shown above.
Those who are looking for an answer to the question «Translational partition function for monatomic gas?» often ask the following questions:
👉 What is partition function of a monoatomic perfect gas?
The partition function is the sum of the Boltzmann factor over all possible states, where is the energy of state . Classically, we can approximate the summation over cells in phase-space as an integration over all phase-space. Thus, (428)
👉 Monatomic ideal gas?
Consider a gas consisting of identical monatomic molecules of mass, enclosed in a container of volume. Let us denote the position and momentum vectors of the th molecule by and, respectively. Because the gas is ideal, there are no interatomic forces, and the total energy is simply the sum of the individual kinetic energies of the molecules:
👉 Is monatomic gas unreactive?
Monatomic gas exists as a single atom and does not bound to each other… There is no chemical bond involved in these gases. They are very unreactive due to the completely full outer valence shell. Since they are inert they don't react easily to form compounds.

Let consider the translational partition function of a monatomic gas. Consider a molecule confined to a cubic box. A molecule inside a cubic box of length L has the translational energy levels given by. (18.1.1) E t r = h 2 ( n x 2 + n y 2 + n z 2) 8 m L 2.
18.1: Translational Partition Functions of Monotonic Gases Since the levels are very closely spaced for translation, a large number of translational states are accessible available for occupation by the molecules of a gas. This result is very similar to the result of the classical kinetic gas theory

18.1: The Translational Partition Function of a Monatomic Ideal Gas. 18.2: Most Atoms Are in the Ground Electronic State at Room Temperature. 18.3: The Energy of a Diatomic Molecule Can Be Approximated as a Sum of Separate Terms. 18.4: Most Molecules Are in the Ground Vibrational State at Room Temperature.
For the moment we assume it is monatomic; the extra work for a diatomic gas is minimal. Remember the one-particle translational partition function, at any attainable temperature, is From this we can obtain the average energy per particle, , and since the particles are non-interacting, the energy of particles in a box is just .
The same procedure applies to polyatomic ideal gases as to diatomic ideal gases. The translation partition function for polyatomic ideal gases has the same exact form as that for diatomic ideal gas or the monatomic ideal gas. (18.7.1) q t r a n s = (2 π M k T h 2) 3 / 2 V N
