The critical temperature of A. B. C. D gases are 190 ~K , 630 K , 261 ~K , 400 ~K respectively. The quantity of gas adsorbed per gram of charcoal at same pressure is least for the gas

Options

  1. AD
  2. BC
  3. CB
  4. DA

Correct answer

D. A

Step-by-step solution

According to the graph of Freundlich adsorption isotherm. There curves indicate that at fixed pressure, there is a decrease in physical adsorption with increase in temperature. The extent of adsorption decreases with increase of temperature so, B > D > C > A A have least quantity of gas adsorbed per gram of charcoal.
