Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What happens when you add more reactant to a system at equilibrium?

💡 Hint: Think of what will happen to the 'balance' of the reaction.

Question 2 Easy

Explain what Le Chatelier's Principle states in your own words.

💡 Hint: Consider how a scale balances when you add weight to one side.

Question 1

What would happen to the equilibrium if a reactant is added?

The equilibrium shifts to the products
The equilibrium shifts to the reactants
No change occurs
It depends on the temperature

💡 Hint: Consider the balance of reactants and products.

Question 2

Le Chatelier's Principle applies to which aspect in equilibrium?

True
False

💡 Hint: Is it about equilibrium balance?

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider the equilibrium system of N2(g) + 3H2(g) ⇌ 2NH3(g). If more H2 is added, calculate the concentrations of all species after equilibrium is re-established, given the initial concentrations are N2 = 1.0 M, H2 = 2.0 M, and NH3 = 0.5 M.

💡 Hint: You’ll need to set up the equilibrium expression and solve for x.

Challenge 2 Hard

In the reaction PCl5(g) ⇌ PCl3(g) + Cl2(g), if the initial concentration of PCl5 is 1.0 M, determine the concentrations of PCl3 and Cl2 at equilibrium when it is found that 0.5 M of PCl5 dissociates.

💡 Hint: Remember the moles of products formed from the moles of reactants decomposed.
