Four gases, A , B , C and D have critical temperatures 5 . 3 , 33 . 2 , 126 . 0 and 154 . 3 K respectively For their adsorption on a fixed amount of charcoal, the correct order is :

Options

  1. AC > D > B > A
  2. BC > B > D > A
  3. CD > C > B > A
  4. DD > C > A > B

Correct answer

C. D > C > B > A

Step-by-step solution

Critical temperature of a gas is the temperature at or above which vapor of the gas cannot be liquefied, no matter how much pressure is applied. The extent of adsorption is directly proportional to the critical temperature of the gas. Higher is the critical temperature of the gas, greater is the extent of adsorption. Order of T c         D > C > B > A Order of adsorption D > C > B > A
