Question

Among SO2, CH4, H2 gases which gas adsorbs more on the charcoal and why?

Answer 1

Answer:

Among SO2, CH4, H2 gases which gas adsorbs more on the charcoal and why? Solution: Sulphur dioxide adsorbs more than methane and hydrogen since the critical temperature of sulphur dioxide is higher than methane and hydrogen.

Answer 2

$SO_2$ adsorbs more on the charcoal.

• The absorption of any gas depends on its critical temperature. As the critical temperature increases the absorption also increases.
• $SO_2$ has a critical temperature of 630K which is higher than the critical temperatures of methane which is 190K and hydrogen which is 33K.
• Thus sulfur dioxide possesses the highest critical temperature and it absorbs more on the charcoal than methane and hydrogen gas.
