Question 1
Explain the effect of decreasing the pressure on the equilibrium of the reaction \( 2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g) \). How would you calculate the new concentrations if you know the original equilibrium concentrations?
💡 Hint: Consider which side has more molecules and apply the equilibrium constant.
Question 2
For an endothermic reaction with an equilibrium constant of 0.2, predict the shift if the temperature is increased. How would you determine the new K?
💡 Hint: What does changing temperature do to K for endothermic reactions?
