What are the characteristics associated with adsorption?
1. ∆G, ∆H, and ∆S are all negative.
2. ∆G and ∆H are negative, but ∆S is positive.
3. ∆G and ∆S are negative, but ∆H is positive.
4. ∆G is negative, but ∆H and ∆S are positive.

A plot of log x/m versus log p for the adsorption of a gas on a solid gives a straight line with slope equal to :
