The Haber Process Flashcards

1
Q

What happens when the temperature of the haber process is lowered?

A

The equilibrium favours the exothermic reaction (forwards), meaning that there is a higher yield.

The rate of reaction is slower

Q

What happens when the pressure of the haber process is increased?

A

The equilibrium favours the forward direction as it creates less molecules. There is a higher yield and rate of reaction but a risk of explosion and it is expensive to maintain

Q

How is the ammonia removed in the haber process?

A

As it is a reversible reaction there is a mix of products and reactants.

The mixture is brought to a lower temperature to liquify it, ammonia becomes a liquid first so is tapped out.

The hydrogen and nitrogen are re used in the process.

Q

Why is the nitrogen and hydrogen used in the haber process re-used?

A

To reduce waste of raw materials

To eventually produce 100% yield
