How to find the W?

Postby Baoying Li 1B » Sun Feb 09, 2020 3:01 pm

How to find the number of ways atoms can be arranged in the Boltzmann’s formula? For instance, the HW problems 4G. 5, why is the W=12 to the 6.02*10^23?

W, or degeneracy, is a measure of how many different positions an atom can be in. For example, the C-O molecule can be in 2 positions (C-O or O-C). W=2. Then we raise the 2 to the power of avogadro's number because you raise the power to the amount of atoms you are analyzing. thus, for one mole (6.02x10^23 molecules) of CO, w=2^(6.02x10^23)

W= #microstates ^ # of particles. There are 12 micro states and 6.02*10^23 is the amount of particles in one mole

W^N or in other words the number of micro states ^ number of particles. If you are given the number of moles then use W^N(a) or number of micro states ^ moles*avogrado's number
