Graph between log x/m and log P is a straight line at angle of `45^(@)` with intercept 0.4771 on y-axis. Calculate the amount of gas adsorbed in gram per gram of adsorbent when pressure is 3 atm.

Text Solution

Verified by Experts

`x/m = KP^(1/n)`
taking log both sides
`log, x/m = log KP^(1/n)`

`log, x/m = log K +1/n log P`
`K =3 (therefore log K = 0.4771)`
`1/n = tan 45^(@) = 1 rArr n = 1`
`x/m = KP^(1/n)`
`x/m = 3(3)^(1/1) = 9`
