Question

Two moles of $N{H}_3$ are introduced into one litre flask in which it dissociates at high temperature as follows:
$2N{H}_3\left(g\right)\rightleftharpoons N_2\left(g\right)+3H_2\left(g\right)$. Determine $K_C$, if at equilibrium $1mole$ of $N{H}_3$ remains.

Answer 1

$2N{H}_3\left(g\right)\rightleftharpoons N_2\left(g\right)+3H_2\left(g\right)$
$200$

$10.51.5$

Now $Kc=\frac{\left[N_2\right][H_2{]}^3}{[N{H}_3{]}^2}$

$=\frac{\left[0.5\right][1.5{]}^3}{[1.0{]}^2}$
$Kc=1.6875mo{l}^2/l^2$
