Chemistry · Secondary 4 · Hard · Ammonia and the Haber process
In the Haber Process, iron is used as a catalyst at about 450 °C when nitrogen and hydrogen react to form ammonia.
Which statement about this iron catalyst is correct?
Which statement about this iron catalyst is correct?
- It speeds up the reaction but does not change the percentage of ammonia at equilibrium.
- It increases the maximum possible percentage of ammonia in the mixture.
- It is used up and must be constantly replaced during the reaction.
- It allows the reaction to reach equilibrium at a lower temperature by raising the activation energy.
