Answer
Finely divided iron
Reason — The speed of the reaction is improved by using a catalyst, which is finely divided iron, obtained by the reduction of iron oxide. It provides a surface for the reaction to occur and lowers the activation energy, allowing the reaction to proceed faster at given temperature and pressure
