Answers
$x=15+y$
$\begin{bmatrix}2(15+y)+3y=29\end{bmatrix}$
$\begin{bmatrix}30+5y=29\end{bmatrix}$
$y=-\frac{1}{5}$
$x=15-\frac{1}{5}$
$x=\frac{74}{5}$
$x=\frac{74}{5},y=-\frac{1}{5}$

A nondegenerate ideal gas of diatomic molecules with a kilomolar mass of 2 kg/kmol and a characteristic rotational temperature of 86 K is adsorbed on the walls of a container, where the binding energy is 0.02 eV. The adsorbed molecules move freely on the walls, and their rotation is confined to the plane of the walls. Calculate the surface density of adsorbed molecules at 12 K if the gas pressure is 103 Pa! What result would you get at 68 K and the same pressure?
