Equilibrium Constants — Quiz

Test your understanding of equilibrium constants with 5 practice questions.

Practice Questions

Question 1

What does the equilibrium constant $K_c$ tell us about a reversible reaction at equilibrium?

Question 2

For the reaction $aA+bB\rightleftharpoons cC+dD$, which expression represents $K_c$?

Question 3

In the equilibrium expression for $K_c$, why are pure solids and pure liquids usually omitted?

Question 4

For the reaction $N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g)$, which equilibrium constant expression is correct?

Question 5

If a reaction has a very large $K_c$ value, what does that usually mean about the equilibrium mixture?
