1. Consider the equilibrium reaction for the formation of sulphur trioxide from sulphur dioxide:

Will the equilibrium amount of SO₃ increase, decrease, or remain the same when an equilibrium mixture of the three gases is subjected to the following changes. Briefly state why. Also state whether the equilibrium constant will increase, decrease, or remain the same in each situation: (4 marks)

a. The temperature is increased

b. Air is added to the mixture without changing the volume and the temperature

c. Nitrogen only is added to the mixture without changing the volume and the temperature

d. Nitrogen is added without changing the total pressure

e. The mixture is compressed at constant temperature
