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. | $\mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2}(\mathrm{~g}) \stackrel{\mathrm{Fe}(\mathrm{s})}{\longrightarrow} 2 \mathrm{NH}_{3}(\mathrm{~g})$ | III. | Chromatography |
| D. | Analytical Application or Adsorption | IV. | Heterogeneous catalysis |
Choose the correct answer from the options given below:
Solution
(A) Physisorption = 20 – 40 kJ/mol and
Chemisorption = 80 – 240 kJ/mol
<br/><br/>(B) Physisorption is multi-layered and
chemisorption is unimolecular layered.
<br/><br/>(C) In heterogeneous catalysis, medium and
catalyst are in different phases.
<br/><br/>(D) Chromatography uses adsorption to
purify/separate mixtures.
