In an adsorption experiment, a graph between `log (x / m)` versus `log P` was found to be linear with a slope `45^circ`. The intercept on the log `(x / m)` axis was found to be `0.3010` .' Calculate thei amount of the gas adsorbed per gram of charcoal undér a pressure of 0.5 atm.

Explanation

Ans: Ereundlich adsorption isotherm "
..
ddotx / m=kp^1 / n Or log x / m=log k+1n cdot log P
..
.therefore. It is of the form .y=m x+C . log x / m v d log P. is
linear with slope .=1n. arid intereept log .K.
..
Slope =1n=tan theta^prime=tan 45^prime prime=1 n=1
