What type of phenomenon is adsorption? What type of reaction is adsorption?
(N/A) Adsorption is a $surface$ phenomenon because it involves the accumulation of molecular species at the surface rather than in the bulk of a solid or liquid.
Adsorption is an $exothermic$ process. In this process,the residual forces of the surface are satisfied,leading to a decrease in surface energy,which is released as heat.

View SolutionGiven below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A:$ Amongst $He$,$Ne$,$Ar$ and $Kr$; $1 \ g$ of activated charcoal adsorbs more of $Kr$.
Reason $R$: The critical volume $V_c \left( cm^3 \ mol^{-1} \right)$ and critical pressure $P_c \left( atm \right)$ is highest for Krypton but the compressibility factor at critical point $Z_c$ is lowest for Krypton.
In the light of the above statements,choose the correct answer from the options given below.
