Oxygen will react with both nitrogen (N) and nitrogen(II) oxide (NO) in reversible reactions.
N.(g)+O(g)
2NO(g)
2NO(g) + O (g)
2NO (g)
a Describe how an increase in pressure will affect the position of equilibrium of
! the reaction between nitrogen and oxygen
ii the reaction between oxygen and nitrogen(II) oxide.
b The reaction between nitrogen and oxygen is endothermic. Describe how an increase in temperature will affect the reaction. Explain your answer.
