Which of the following gases is adsorbed most by activated charcoal?A. `SO_(2)`B. `CH_(4)`C. `H_(2)`D. All are equally adsorbed |
|
Answer» Correct Answer - A Gases with higher critical temperatures are readily adsorbed. Thus `1gram` of activated charcoal adsorbs more `SO_(2)` (critical temp.`630K`) than methane (critical temp `190K`) which is still more than dhiydrogen (critical temperature `33K`). Notice that the value of critical temop-erature isd directly related to the molar mas of gas. |
