Adsorption is the tendency of accumulation of molecular species at the surface of solid or liquid. Depending upon the nature of bonds or forces of attraction between adsorbate and adsorbent. It is classified between physisorption and chemisorption.
Which of the following gas molecules have maximum value enthalpy of physisorption?

A

`C_(2)H_(6)`

B

Ne

C

`H_(2)O`

D

`H_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Since, `H_(2)O` can be liqufied easily, hence it will have the maximum enthalpy of physisorption.
