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)

Options

A. "log"k
B. `(n)/(1)`
C. 2k
D. n

Answer

B

Explanation

According to Freundlich adsorption isotherm.
`(x)/(m)=kP^((1)/(n))`
`"log"_(10)((x)/(m))=(1)/(n)"log"_(10)P+"log"_(10)k`
This is the equation of straight line of type `y=mx+c` Hence slope is 1/n (m) and intercept is `"log"_(10)k`
