Question

Shown below are adsorption isotherms for a gas '

\mathrm{X}

' at temperatures

\mathrm{T}_1, \mathrm{~T}_2

and

\mathrm{T}_3

:

Shown below are adsorption isotherms for a gas ' X ' at temperatures T_1, ~T_2 and T_3 : p and (x)/(m) represent

p

and

\frac{x}{m}

represent pressure and extent of adsorption, respectively. The correct order of temperatures for the given adsorption is:

Quantrex Academy · Accepted Answer

Correct answer: B. T_3>T_2>T_1

' x ' is mass of gas adsorbed on mass ' m ' of the adsorbent at pressure ' p '. The curves in the given adsorption isotherm indicates that at a fixed pressure, there is decrease in physical adsorption with increase in temperature and vice versa. So, the correct order of temperature is : T_3>T_2>T_1
