Question 1
A sealed container with reactants A and B reaches equilibrium. After adding more A, describe the changes in concentration of A and B and the shift in equilibrium position.
💡 Hint: Consider how the system compensates for the added reactant.
Question 2
In an industrial process, the equilibrium for the synthesis of sulfur trioxide (SO₃) is represented by 2SO₂(g) + O₂(g) ⇌ 2SO₃(g). If the total pressure is increased, what will happen to the position of equilibrium and why?
💡 Hint: Remember how pressure affects moles of gas in equilibrium.
