i) Write down the Equation for the Haber-Bosch process. Stating clearly the catalyst used. ii) Explain why high pressures are used for this reaction in industry iii) Explain the importance of the catalyst

i) N 2 (g) + 2H 2 (g) = 2NH 3ii) Le Chatelier’s Principle : If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change. Pressure is a result ...
