Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What does K indicate about a reaction?

  • It shows the speed of the reaction
  • It indicates product/reactant ratio at equilibrium
  • It measures temperature changes

💡 Hint: Remember what K represents!

Question 2

True or False: Le Chatelier’s Principle applies only to closed systems.

  • True
  • False

💡 Hint: Think about the conditions needed for equilibrium.

Challenge Problems

Push your limits with challenges.

Question 1

If 1.0 mol of A and 3.0 mol of B are mixed in a closed container, and equilibrium is established with products C and D at a concentration of 0.5 M for C and 0.5 M for D, what is K? Also, if the concentration of A is later increased to 2.0 M, what will happen to the equilibrium?

💡 Hint: Remember the equilibrium expression and Le Chatelier’s Principle.

Question 2

A reaction system at equilibrium has the following concentrations: [N2] = 0.2 M, [H2] = 0.6 M, [NH3] = 0.4 M. If the pressure is decreased, describe the shift in equilibrium.

💡 Hint: Consider how shifts are influenced by changes in pressure.
