Question

Given: 
 (i) $N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g) \quad K_1$ 
 (ii) $N_2(g) + O_2(g) \rightleftharpoons 2NO(g) \quad K_2$ 
 (iii) $H_2(g) + \frac{1}{2}O_2(g) \rightleftharpoons H_2O(g) \quad K_3$ 
 What is $K_4$ for $2NH_3(g) + \frac{5}{2}O_2(g) \rightleftharpoons 2NO(g) + 3H_2O(g)$?
