Q: What is the equilibrium constant expression for the reaction N2(g) + 3H2(g) ⇌ 2NH3(g)?

Solution: The equilibrium constant Kc is given by the ratio of the concentration of products to reactants, raised to the power of their coefficients.

Steps: 5

Step 1: Identify the reactants and products in the reaction. Here, the reactants are N2 and H2, and the product is NH3.
Step 2: Write the general form of the equilibrium constant expression, Kc = [products]^[coefficients] / [reactants]^[coefficients].
Step 3: For the given reaction, the products are 2NH3, so we write [NH3]^2.
Step 4: The reactants are N2 and 3H2, so we write [N2] and [H2]^3.
Step 5: Combine these into the Kc expression: Kc = [NH3]^2 / ([N2] * [H2]^3).
