If x gram of gas is adsobed by m gram of adsorbent at pressure P the plot of log `(x)/(m)` versus log P is linear .the slope of the plot is :
(n and k are constant and n `gt` 1)

A

log k

B

n

C

2k

D

`1//n`

Text Solution

Verified by Experts

The correct Answer is:
D
According to Freundlich adsorption isotherms, `(x)/(m)=kP^(1//n)`
Taking log on both sides, `"log"(x)/(m) = log k +(1)/(n) log P`
A graph between `"log"(x)/(m)` vs logP gives a straight line with slope equal to `(1)/(n)`.
