Vedclass · Answer

(D) When a mixture of gases is introduced into a closed vessel containing charcoal,the charcoal acts as an adsorbent. As time passes,the gas molecules get adsorbed onto the surface of the charcoal. Since the number of gas molecules in the gaseous phase decreases due to adsorption,the pressure exerted by the gas mixture in the vessel decreases with time until it reaches an equilibrium state. Therefore,the graph showing a decrease in pressure over time is the correct representation.

$A$ mixture of gases $O_2$,$H_2$,and $CO$ are taken in a closed vessel containing charcoal. The graph that represents the correct behaviour of pressure with time is
