Answer - Correct option is - (a) (iv) (ii) (iii) (i)
Sulphuric acid is produced by contact process. Raw materials are sulphur or iron pyrites, which are heated in excess of oxygen to obtain product.
Steel was earlier produced by Bessemer’s process. It used molten pig iron heated in furnace. It aims to remove impurities by oxidation.
Leblanc process produces soda ash or sodium carbonate. It produces product from common salt named as sodium chloride.
Ammonia production is done by Haber's process. The process uses hydrogen and nitrogen gas to form ammonia. The ratio used is 3:1.
