(a)[2]
Predict and explain how lowering the pressure changes the position of this equilibrium. The temperature is kept constant.
(b)[2]
Predict and explain how raising the concentration of chlorine changes the position of this equilibrium.
(c(i))[1]
Describe how the make-up of this equilibrium mixture varies with temperature.
(c(ii))[1]
Explain what this shows about the energy change in this reaction.
(d)[1]
How is the position of equilibrium changed by the presence of a catalyst?
(e)[2]
Explain why the rate of this reaction increases when the temperature rises.
(f)[1]
