Question: If the equilibrium constant Kc for the reaction A ⇌ B is 0.1, what can be inferred about the concentrations of A and B at equilibrium?

Options:

Correct Answer: A > B

Solution:

Since Kc < 1, it indicates that at equilibrium, the concentration of A is greater than that of B.

If the equilibrium constant Kc for the reaction A ⇌ B is 0.1, what can be inferred about the concentrations of A and B at equilibrium?

If the equilibrium constant Kc for the reaction A ⇌ B is 0.1, what can be inferred about the concentrations of A and B at equilibrium?

Step 1: Understand what Kc means. Kc is the equilibrium constant that tells us the ratio of the concentrations of products to reactants at equilibrium.
Step 2: Identify the reaction. The reaction given is A ⇌ B, where A is the reactant and B is the product.
Step 3: Note the value of Kc. In this case, Kc = 0.1.
Step 4: Compare Kc to 1. Since 0.1 is less than 1, it suggests that the reactants (A) are favored over the products (B) at equilibrium.
Step 5: Conclude about concentrations. Because Kc < 1, we can infer that the concentration of A is greater than the concentration of B at equilibrium.

Equilibrium Constant (Kc) – The equilibrium constant (Kc) indicates the ratio of concentrations of products to reactants at equilibrium. A Kc value less than 1 suggests that reactants are favored over products.
