Which of the following statement is incorrect regarding physisorption?

A particular adsorption process has the following characteristics : (i) It arises due to van der Waals forces and (ii) it is reversible. Identify the correct statement that describes the above adsorption process :

The most appropriate method of making egg-albumin sol is:

$$3$$ g of activated charcoal was added to $$50$$ mL of the acetic acid solution $$(0.06\ N)$$ in a flask. After an hour, it was filtered and the strength of the filtrate was found to be $$0.042\ N$$. The amount of acetic acid adsorbed (per gram of charcoal) is :

Which one of the following is not a property of physical adsorption?

Peptization is a :

Among the following, the surfactant that will form micelles in aqueous solution at the lowest molar concentration at ambient conditions is :

Methylene blue is adsorbed on activated charcoal at $$25^{0}C$$ from its aqueous solution. Which is the correct statement for this process?

The qualitative sketches I, II and III given below show the variation of surface tension with molar concentration of three different aqueous solutions of $$KCl, CH_{3}OH$$ and $$CH_{3}(CH_{2})_{11}OSO_{3}^{-} Na^{+}$$ at room temperature.

Rate of physisorption increases with:
