Problem

For the surface adsorption model of the preceding Example, investigate the mean number of molecules adsorbed per site (

\bar{n}

) in the limit

T \to 0

, for all combinations of signs and relative magnitudes of

(\varepsilon_1 + \mu_0)

and

(\varepsilon_2 + 2\mu_0)

, where

\mu_0

is the value of the

\mu

of the gas at

T = 0

. Explain these results heuristically.
