In an Adsorption experiment a graph between log `x//m` versus log P was found to be linear with a slope of `45^(@)` the intercept of the log `x//m` was found to be `0.3010`. Calculate the amount of gas adsorbed per gm of charcoal under a pressure of `0.6` bar.

Text Solution

Verified by Experts

The correct Answer is:
`1.2`
According to frendulish equation `x/m=KxxP^(1//n)`
`"log" x/m=1/n "log" P+log K`
compare with straight line equation ltbtgt `1/n= tan `45^(@), n=1`
intercept `loh K=0.03010`
`K=2`
Put the value of K, P & n in freundlich equation `x/m=KxxP^(1//n)=2xx(0.6)^(1)=1.2`
