A graph between (x/m) vs log p gives a straight lien with slope equal to `45^@` and interecept on the log (x/m) axis as 0.3. Calculate the amount of gas adsorbed per gram of charcoal at a pressure of 0.95 atm.

Text Solution

Verified by Experts

Freundlich isotherm equation : `x//m = kp^(1//n) , i.e., log (x//m) = log k + 1//n log p`
Given Slope = tan `45^@` = 1 , Intercept = 0.3, i.e log k = 0.3 or k = 2.0 k, Pressure p = 0.95 atm
Extent of adsorptoin (amount of gas adsorbed per gram of charcoal), `x// m = k^(1//n) = 2.0. (0.95)^1 = 1.9`
