Write the definition of $K_p$ for the following equilibria: $2POCl_3(g)$ $2PCl_3(g)$ $+$ $O_2(g)$ $2PCl_3(g)$ $+$ $O_2(g)$ $2POCl_3(g)$ $Br_2(g)$ $+$ $Cl_2(g)$ $2BrCl$ $N_2(g)$ $+$ $2O_2(g)$ $N_2O_4$
$K_p$ $=\frac{p_{PCl_3}^2p_{O_2}}{p_{POCl_3}^2}$ $K_p$ $=$ $\frac{p_{POCl_3}^2}{p_{PCl_3}^2p_{O_2}}$ $K_p$ $=$ $\frac{[p_{BrCl}]^2}{p_{Br_2}p_{Cl_2}}$ $K_p$ $=$ $\frac{p_{N_2O_4}}{p_{N_2}p_{O_2}^2}$
$2PCl_3(g)$ $+$ $O_2(g)$
$2PCl_3(g)$ $+$ $O_2(g)$
