Identify the gas which is readily adsorbed by activated charcoal
Options
(a) N₂
(b) SO₂
(c) H₂
(d) O₂
Correct Answer:
SO₂
Explanation:
In general, more easily liquefiable gases ( i.e. higher critical temperatures) are readily adsorbed as van der Waal’s forces are stronger near the critical temperatures. Thus, 1 g of activated charcoal adsorbs 380 ml of sulphur dioxide (critical temperature 157⁰C). 16 ml of methane (critical temperature – 83⁰C and 4.5 ml of hydrogen(critical temperature – 240⁰C.
