Vedclass · Answer

(A) When an iron rod is exposed to a moist atmosphere,it undergoes corrosion,commonly known as rusting. This process involves the formation of hydrated ferric oxide $(Fe_2O_3 \cdot xH_2O)$ on the surface of the iron. Since this involves the formation of chemical bonds between the iron surface and the oxygen/water molecules,it is classified as a surface phenomenon known as chemisorption.

When an iron rod is subjected to an atmosphere having a very high content of moisture,which process is predominant?
