Ammonia gas $($A$)$ diffuses through a uniform tube $0\mathrm{.}10$m long containing N$2$ gas $($B$)$ at $1\mathrm{.}0132$x$105$ Pa pressure and $298$K$.$ At point $1,$ PA$1=1\mathrm{.}013$x$104$ Pa and at point $2,$ PA$2=0\mathrm{.}507$x$104$ Pa$.$ DAB $=0\mathrm{.}230$x$10-4$ m$2/$s$.$ Calculate the flux J$*$A and J$*$B at steady state $($JA $=$ JB$).$ Given:

PA$1=1\mathrm{.}013$x$104$ Pa; PA$2=0\mathrm{.}507$x$104$ Pa; DAB $=0\mathrm{.}230$x$10-4$ m$2/$s; T $=298$K P $=1\mathrm{.}0132$x$105$ Pa; x$2$ x$1=0\mathrm{.}10$ m; R $=8314\mathrm{.}3$ m$3$ Pa$/$kgmol K
