In an absorption experiment a graph between log `x/m` versus log `P` was fond to be linear with a slope of `45^@)`. The intercept on the log `x/m` axis was found to `0.70`. Calculate the amount of gas adsorbed per gram of charcoal under a pressure of `1` atm `[log5=0.70]`

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`
