Comprehension
: A chemist was studying the phenomenon of adsorption by putting blood charcoal in \( \mathrm{KCl} \) solution. \( \mathrm{He} / \) she observed difference in behaviour with dilute \( \mathrm{KCl} \) solution and with concentrated \( \mathrm{KCl} \) solution. \( \mathrm{He} \) /she also made a detailed study of the adsorption of gases on solid adsorbents. Helshe observed that at the same temperature, different amounts of gases like \( \mathrm{NH}_{3}, \mathrm{SO}_{2}, \mathrm{CO}_{2}, \mathrm{HCl} \) were adsorbed by the same amount of the adsorbent. He/she further studied the effect of temperature on adsorption and observed that in some cases, adsorption showed a regular trend while in some other cases, the trend was not regular.
The correct order of adsorption of gases studied will be
(a) \( \mathrm{NH}_{3}\mathrm{SO}_{2}\mathrm{CO}_{2}\mathrm{HCl} \)
(b) \( \mathrm{CO}_{2}\mathrm{SO}_{2}\mathrm{NH}_{3}\mathrm{HCl} \)
(c) \( \mathrm{SO}_{2}\mathrm{NH}_{3}\mathrm{HCl}\mathrm{CO}_{2} \)
(d) \( \mathrm{HCl}\mathrm{SO}_{2}\mathrm{NH}_{3}\mathrm{CO}_{2} \)
