The first two steps in the industrial synthesis of nitric acid produce nitrogen dioxide from ammonia: 4 NH3(g) +50₂ (g) = 4 NO(g) + 6H₂O(g) K₁ K2 2 NO(g) + O₂(g) 2 NO₂ (g) = The net reaction is: K 4 NH3(g) +70₂ (g) 4NO₂(g) + 6H₂O(g) Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants K, and K₂. If you need to include any physical constants, be sure you use their standard symbols, which you'll find in the ALEKS Calculator. K = 0 0.0 00 09 ? olo X G
