Finely divided iron combines with `CO` to give

Dinitrogen and dihydrogen combine to form ammonia in Haber process in presence of finely divided iron along with K_2O and Al_2O_3 . Here, K_2O and Al_2O_3 are

Give reasons for the following . Finely divided iron catalyst does not affect the percentage yield of ammonia in Haber 's process.

Statement-1:Finely divided iron does not form ferric chloride with hydrochloric acid. Statement-2:Hydrochloric acid produces hydrogen gas with iron.
