Q. Assertion :Physical adsorption increases with increase in temperature. Reason: Physical adsorption is an endothermic process.

Q. Assertion :Langmuir adsorption isotherm is based on the concept of monolayer adsorption. Reason: At high pressure, the surface is fully occupied by adsorbate molecules and the further increase in pressure does not effect adsorption.

Q. Observe the given adsorption isotherm carefully and choose the correct option.
(i) These curves indicate that at a fixed temperature, there is a decrease in physical adsorption with increase in pressure.
(ii) These curves always seem to approach saturation at high pressure.
(iii)

\frac{x}{m} = k p^{1 / n}

(n>1) is generally represented by this isotherm.
(iv) These curves indicate that at a fixed pressure, there is a decrease in physcial adsorption with increase in temperature.

Q. Adsorption of a gas follows the equation

\frac{x}{m} = k P^{1 / 2}

Then the effect of pressure & temperature on physical adsorption of gas on solid is:

Q. In Langmuir adsorption isotherm, the extent of adsoption increases linearly with pressure at
