Answer:

The answer is " $k=k_1k_{2}^2$ "

Step-by-step explanation:

For point 1:

$4NHH_3 \ (g) +5O_2\ (g) \leftrightharpoons 4NO\ (g) +6H_2O \ (g)..................k_1\\\\$

For point 2:

$2 \times(2\ NO\ (o)+O_2 \ (g) \leftrightharpoons 2NO_2\ (g)) ..................K_2\\\\$

Adding $k_1$ equation and multiply by 2 in the equation $k_2$ so we get $\to 4NH_3\ (g) +7 O_2\ (g) \leftrightharpoons 4 NO_2\(g) +6H_2O\ (g)....... k\\\\k= k_1\times k_{2}^2\\\\k=k_1k_{2}^2\\\\$
