Questions & Step-by-Step Solutions
What is the equilibrium constant expression for the reaction: 2A + B ⇌ C?
Correct Answer: K = [C]/([A]^2[B])
Step 1: Identify the reactants and products in the reaction. Here, the reactants are 2A and B, and the product is C.
Step 2: Write the general form of the equilibrium constant expression, which is K = [products] / [reactants].
Step 3: For each substance, use its concentration in square brackets. The product C is in the numerator, and the reactants A and B are in the denominator.
Step 4: Since there are 2 moles of A, we raise its concentration to the power of 2. The concentration of B remains as is.
Step 5: Combine these into the final expression: K = [C] / ([A]^2[B]).
