Verified Solution • 2025–26 Session moderate

The graph of

\log \frac{x}{m}

vs

\log \mathrm{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}

is _________

\times 10^{-1}

(Nearest integer).

Given:

\log 2=0.3010

Accepted Answer

$\frac{1}{n} = \tan (45^{\circ})$

$∴$ $n = 1$

$\log k = 0.602$

$∴$ $k = 4$

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

$= 4 \times 0.4 = 1.6$ g
