What is the equilibrium constant expression for the reaction: aA + bB ⇌ cC + dD?
K = [C]^c [D]^d / [A]^a [B]^b
K = [A]^a [B]^b / [C]^c [D]^d
K = [C]^c [D]^d
K = [A]^a [B]^b
The equilibrium constant K is defined as the ratio of the concentration of products to the concentration of reactants, each raised to the power of their coefficients in the balanced equation.

Q
Q: What is the equilibrium constant expression for the reaction: aA + bB ⇌ cC + dD?
Solution: The equilibrium constant K is defined as the ratio of the concentration of products to the concentration of reactants, each raised to the power of their coefficients in the balanced equation.
Steps: 6
Step 1: Identify the balanced chemical equation: aA + bB ⇌ cC + dD.
Step 2: Recognize that 'A' and 'B' are reactants, and 'C' and 'D' are products.
Step 3: Write the expression for the equilibrium constant K.
Step 4: For the products (C and D), write their concentrations raised to the power of their coefficients: [C]^c and [D]^d.
Step 5: For the reactants (A and B), write their concentrations raised to the power of their coefficients: [A]^a and [B]^b.
Step 6: Combine the products and reactants into the equilibrium constant expression: K = ([C]^c * [D]^d) / ([A]^a * [B]^b).
