Which of the following statements is incorrect?

A

Freundlich equation for adsorption of gases `(xg)` on a solid `(mg)` at constant temperature can be expressed as
`log.(x)/(m)=logK+(1)/(n)logP`

B

If a liquid is dispersed in solid medium then this is called as gel

C

Ziegler-Natta catalyst `[Al(C_(2)H_(5))_(3)+TiCl_(4)]` is used for linear polymerisation to prepare high density polythylene `(HDPE)`

D

Enthalpy of adsorption is low and positive

Text Solution

Verified by Experts
