In an adsorpion experiment, a graph between log (x/m) versus log P was found to be linear with a slope of `45^@`. The intercept on the yaxis was found to be 0.301. Calculate the amount of the gas adsorbed per gram of charcoal under a pressure of 3.0 atm.

Text Solution

Verified by Experts

The correct Answer is:
6
Given : slope `= 45^@` intercept = 0.301, P = 3.0 atm
Thus `(1)/(n) = tan theta = tan 45^@ = 1 or n=1" "log K = 0.301 or K = "antilog" 0.301 =2`
At = P = 3 atm , `(x)/(m) = KP^(1//a) = 2 xx (3)^1 = 6`
