Boltzmann Equation

Postby JennyCKim1J » Tue Feb 06, 2018 8:56 am

Is Kb simply equal to R, or is it only when we are calculating W for 1 mole? If it is only for 1 mole, what is Kb?

Kb is equal to 1.381 x 10^-23 J/K

Kb is a constant, at 1.381 x 10^-23 J/K. When calculating W for 1.00 mole where there are n states for each molecule, you raise n to the power of 6.02x10^23 (Avagadro's Number), so for 1.00 mole, you can
have Entropy S= (6.02x10^23) x Kb ln n, where there are n states for the molecule.
