Question: What is the equilibrium constant (Kc) expression for the reaction: 2A + B ⇌ C?

Options:

Kc = [C] / ([A]^2[B])
Kc = [A]^2[B] / [C]
Kc = [C] / [A]^2
Kc = [A]^2 / ([B][C])

Correct Answer: Kc = [C] / ([A]^2[B])

Solution:

The equilibrium constant Kc 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. For the reaction 2A + B ⇌ C, Kc = [C] / ([A]^2[B]).

Questions & Step-by-Step Solutions

What is the equilibrium constant (Kc) expression for the reaction: 2A + B ⇌ C?

Step 1: Identify the balanced chemical equation. In this case, it is 2A + B ⇌ C.
Step 2: Identify the products and reactants. Here, C is the product, and 2A and B are the reactants.
Step 3: Write the expression for the equilibrium constant Kc. It is the concentration of products divided by the concentration of reactants.
Step 4: For each substance, raise its concentration to the power of its coefficient in the balanced equation. C has a coefficient of 1, A has a coefficient of 2, and B has a coefficient of 1.
Step 5: Write the Kc expression: Kc = [C] / ([A]^2[B]).
