 Okay, let's try this one. Let's try this one real quick and we'll go back. So, write the equilibrium constant for this reaction. So, equilibrium constant KdQ, remember, is the concentration of the product over the concentration of the reactant. Only if they're gaseous or aqueous. If they're solids or liquids, you're not going to put them in the equilibrium expression. Okay, so, the products in this reaction are ammonia gas that we're going to do Nx3. And the coefficient of ammonia is 2, so we're going to make it the superscript there. So it's Nx3 squared. And then we're going to come over to the reactant side. N2 times H2. And notice H2 as a coefficient of 3. So we're going to Q H2 like that. Okay, so that would be the first, that would be it.
