The following equilibrium constants are given

$${N_2} + 3{H_2}$$ $$\rightleftharpoons$$ $$2N{H_3}$$; $${K_1}$$

$${N_2} + {O_2}$$ $$\rightleftharpoons$$ $$2NO$$; $${K_2}$$

$${H_2} + {1 \over 2}{O_2}$$ $$\rightleftharpoons$$ $${H_2}O$$; $${K_3}$$

The equilibrium constant for the oxidation of 2 mole of NH₃ to give NO is

$${K_1} . {{{K_2}} \over {{K_3}}}$$

$${K_2}.{{K_3^3} \over {{K_1}}}$$

$${K_2}.{{K_3^2} \over {{K_1}}}$$

$$K_2^2.{{K_3^{}} \over {{K_1}}}$$
