... 2 NH3 (g) ⇌ N2 (g) + 3 H2 (g) At 450.˚C, Kc = 6.30. An unknown quantity of NH3 is placed in a reaction flask (with no N2 or H2) and is allowed to come to equilibrium at 450. °C. The equilibrium concentration of H2 is then determined to be 0.342 M. Determine the initial concentration of NH3 placed in ...
