Question
Write expression of $\text{K}_{\text{c}}$ for reaction:
$\text{N}_2(\text{g})+3\text{H}_2(\text{g})\rightleftharpoons2\text{NH}_3(\text{g})$
Give units of K.
✓

Answer

$\text{K}=\frac{[\text{NH}_3]^2}{[\text{N}_2][\text{H}_2]^3}$
$=\frac{(\text{mol L}^{-1})^2}{(\text{mol}^{-1})(\text{mol L}^{-1})^3}=\text{L}^2\text{mol}^{-2}$
