The gases amonia and nitrogen are stored in tank $1$ and $2.$ The tanks are maintained at constant pressure of $1,0132$x$105$ Pa and temperature of $298$K$.$ A uniform tube $(0\mathrm{.}1$ m long$)$ connects the tanks. The partial pressure of A at point $1$ is $1,013$x$104$ Pa and, at point $2$ is $0,507$x$104$ Pa$.$ The diffusivity is $0\mathrm{.}230.10-4$m$/$s and R$=8314$ m Pa$/$Kgmol$.$K$.$
