The equilibrium constants of the following are: \( \text{N}_2 + 3\text{H}_2 \rightleftharpoons 2\text{NH}_3 \; ; \text{K}_1 \) \( \text{N}_2 + \text{O}_2 \rightleftharpoons 2\text{NO} \; ; \text{K}_2 \) \( \text{H}_2 + \frac{1}{2}\text{O}_2 \longrightarrow \text{H}_2\text{O} \; ; \text{K}_3 \)\nThe equilibrium constant (K) of the reaction: \( 2\text{NH}_3 + \frac{5}{2}\text{O}_2 \stackrel{\text{K}}{\rightleftharpoons} 2\text{NO} + 3\text{H}_2\text{O} \), will be
