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.

Q. Rate of physical adsorption increases with?

Q. Assertion :

N_{2}

is adsorbed on iron surface at

83

K which decreases rapidly with increase in temperature and at room temperature, practically no adsorption of

N_{2}

occurs. The adsorption, however, becomes significant at

773

K. Reason: At lower temperature, adsorption of

N_{2}

molecules on iron surface is physisorption and at high temperatures,

N_{2}

shows chemisorption of

N

atoms on iron surface.
