Haber Process

Question 1

What is a reversible reaction?

Answer 1

A reaction that can go forwards and backwards

Question 2

Explain what is meant by dynamic equilibrium?

Answer 2

It means the reactants and products will reach a certain balance and stay there.

Question 3

What two factors can shift the equilibrium?

Answer 3

Temperature and pressure

Question 4

Explain how temp & pressure shift the equilibrium

Answer 4

If you raise the temperature the endothermic reaction will increase to use up the heat. If you reduce the temp the exothermic reaction will increase to give out more heat
Raising the pressure encourages the reaction due to the particles having less space

Question 5

Describe the conditions used in industry for the Haber Process

Answer 5

200 atms pressure this favours the forward reaction but reduces cost in equipment.
450’C temperature this maintains the forward reaction but offers a moderate % yield

Question 6

Name the catalyst used in the Haber process and describe it’s role

Answer 6

Iron- to increase the reaction between H2 & N2
