(a(i))[1]
Explain why a reversible reaction has to be carried out in a closed system before an equilibrium mixture can form.
(a(ii))[2]
Predict what happens to the equilibrium position when the temperature is reduced and the pressure stays constant. Explain your answer.
(a(iii))[2]
Predict what happens to the equilibrium position when the pressure is reduced and the temperature stays constant. Explain your answer.
(b)[2]
Predict what happens to the rate of the backward reaction when the temperature is lowered and the pressure stays constant. Explain your answer.
(c)[2]
Predict what happens to the rate of the backward reaction when the pressure is increased and the temperature stays constant. Explain your answer.
