 $\begin{array}{cc}\Delta n_{\text{g}}={\text{n}}_{\text{p}}-{\text{n}}_{\text{r}}& \{\begin{array}{l}{\text{n}}_{\text{p}}=\text{number of moles of products (gaseous)}\\ {\text{n}}_r=\text{number of moles of reactants (gaseous)}\end{array}\end{array}$  $\begin{array}{c}\Delta {\text{n}}_{\text{g}}=\mathrm{}\mathrm{}\mathrm{}\mathrm{}\mathrm{}\mathrm{}\mathrm{}2-4\\ =-2\end{array}$ ${\text{K}}_{\text{C}}=\frac{{\text{K}}_{\text{P}}}{{\left(\text{RT}\right)}^{\Delta {\text{n}}_{\text{g}}}}$
  $\begin{array}{c}K\text{c}=\frac{1.44\times {10}^{-5}}{{\left(0.082\times 773\right)}^{-2}}\end{array}$          (T in K and R in L atm mole^-1 $K^{-1}$).
