Le Chatlier's Principle

Which way will the equilibrium shift if you remove AC? 2AB (s) + C2 (g) ⇌ AC (g) + BC (g)

• Towards the products

• Towards the reactants

• It will stay the same

• Towards the products
• Towards the reactants
• It will stay the same

Which way will the equilibrium shift if you increase the volume? 2A (s) + 2B (l) ⇌ 2AB (aq)

• Towards the products
• Towards the reactants
• It will stay the same
