The critical temperature of A. B. C. D gases are \(190 \mathrm{~K}, 630\) \(\mathrm{K}, 261 \mathrm{~K}, 400 \mathrm{~K}\) respectively. The quantity of gas adsorbed per gram of charcoal at same pressure is least for the gas
- A D
- B C
- C B
- D A
Answer & Solution
Correct Answer
(D) A
Step-by-step Solution
Detailed explanation
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…
