Questions & Step-by-Step Solutions
What is the equilibrium constant (Kc) for the reaction: A + B ⇌ C + D? (2022)
Step 1: Identify the balanced chemical equation. In this case, it is A + B ⇌ C + D.
Step 2: Write down the expression for the equilibrium constant Kc. It is Kc = [C]^c * [D]^d / [A]^a * [B]^b.
Step 3: Identify the coefficients of each substance in the balanced equation. Here, A and B have coefficients of 1, and C and D also have coefficients of 1.
Step 4: Substitute the coefficients into the Kc expression. Since all coefficients are 1, Kc = [C]^1 * [D]^1 / [A]^1 * [B]^1.
Step 5: Simplify the expression. This gives Kc = [C] * [D] / ([A] * [B]).
Step 6: This is the final expression for the equilibrium constant Kc for the reaction A + B ⇌ C + D.
