Langmuir Adsorption - Statistical Mechanics

[@rameshkalagnanam2946]

Prof. Stuart - you videos are absolutely a class of their own! You are a very effective teacher.

[@PhysicalChemistry]

That's very kind

[@sla4214]

such a good source

[@carmenramosvellon2182]

What if we want to know the average number of adsorbed atoms and their energy?

[@PhysicalChemistry]

@@carmenramosvellon2182 The total number of adsorbed atoms will be proportional to the total area. That's an extensive quantity, for which Theta is a corresponding intensive quantity

[@xinruizhao4390]

What is this k in KT though?

[@xinruizhao4390]

Was that universal gas constant?

[@PhysicalChemistry]

Yes, this k is Boltzmann's constant (k = 1.38x10⁻²³ J/K) which is the same as the gas constant. The equation that uses kT is introduced in the previous video: kzbin.info/www/bejne/r3-6e5aQfs2gpM0 And the Boltzmann constant is discussed in more detail in an earlier video: kzbin.info/www/bejne/qXqZemaAj5mnhpY
