Question

When a graph is plotted between log (x/m) and log P, it is a straight line that makes an angle of ${45}^{\circ }$ with the X-sxis and an intercept 0.4771 on the Y-axis. If the initial pressure is 0.3 atm, what will be the amount of gas adsorbed per gm of adsorbent?

Answer 1

$log\frac{x}{m}=logk+\frac{1}{n}logP$

$\frac{1}{n}=tan{45}^{\circ }logk=0.4771$

$n=1k=3$

$\frac{x}{m}=3\times (0.3{)}^1$

$\frac{x}{m}=0.9$
