Match List I with List II

List I		List II
A	Physisorption	I	Single Layer Adsorption
B	Chemisorption	II	$20-40 \mathrm{kJ} {\mathrm{mol}}^{-1}$
C	${\mathrm{N}}_2\left(\mathrm{g}\right)+3{\mathrm{H}}_2\left(\mathrm{g}\right)\stackrel{\mathrm{Fe}\left(\mathrm{s}\right)}{⟶}2{\mathrm{NH}}_3\left(\mathrm{g}\right)$	III	Chromatography
D	Analytical Application or Adsorption	IV	Heterogeneous catalysis

Choose the correct answer from the options given below:

(A) In physisorption, the enthalpy heat is low and lies between $20 - 40 \mathrm{kJ} {\mathrm{mol}}^{-1}$. In physisorption, multilayers of adsorbed particles are formed.

(B) In chemisorption, the enthalpy heat is high and lies within the range of $40 - 200 \mathrm{kJ} {\mathrm{mol}}^{-1}$.  In chemisorption, a monolayer of adsorbed particles is formed.

(C) ${\mathrm{N}}_2\left(\mathrm{g}\right)+3{\mathrm{H}}_2\left(\mathrm{g}\right)\stackrel{\mathrm{Fe}\left(\mathrm{s}\right)}{⟶}2{\mathrm{NH}}_3\left(\mathrm{g}\right)$

Heterogeneous catalysts occupy a different phase. Generally, heterogeneous catalysts are solid compounds that are added to liquid or gas reaction mixtures. Fe is used as a heterogeneous catalyst in the Haber process.

(D) In the process of adsorption chromatography, different compounds are adsorbed on the adsorbent to different degrees based on the absorptivity of the component. 

So, the correct matching is A-IV, B-II, C-III, D-I.
