What happens when you increase the concentration of a reactant in a reversible reaction?
Think about what 'more reactant' means for product formation.
If some product is removed from a reaction at equilibrium, what will happen?
Removing something tends to make the system ‘work harder’ to replace it.
What is the primary effect of adding more reactant to a system at equilibrium?
Think about which side of the equation you are enhancing.
True or False: Removing a product from a reaction at equilibrium will shift the equilibrium to the left.
If you remove something, what does the system want to do?
You have the reaction 2SO₂ + O₂ ⇌ 2SO₃ with Kc calculated as 25 at a specific temperature. If SO₂ is added, what will happen to Kc and the position of equilibrium?
Understand the difference between Kc and the actual equilibrium position.
If both a reactant and a product are significantly altered, which one influences the equilibrium more effectively? Explain why.
Look at the stoichiometry of the reaction!
