The graph of

\log \frac{x}{m}

\log p

for an adsorption process is a straight line inclined at an angle of

45^{\circ}

with intercept equal to 0.6020 . The mass of gas adsorbed per unit mass of adsorbent at the pressure of _____

0.4 \mathrm{~atm}

\times 10^{-1}

(Nearest integer).

Given :

\log 2=0.3010

View answer and explanation

Correct option: A

Option A (16) is correct because the mass of gas adsorbed per unit mass of adsorbent is calculated using the Freundlich isotherm, resulting in 1.6, which is 16 × 10^-1.
