In the Freundlich isotherm `((x)/(m)=k _(p) ^(1//n))` plot of log `""x/m` vs log p, the intercept is (where, x,m,p and k are mass of the gas, mass of adsorbent, pressure and constant which depend on the nature of the adsorbent, respectively)

Options

A. k
B. `log k `
C. `e ^(k)`
D. `ln ""(1)/(k)`

Answer

B

Explanation

For Freundlich adsorptin isotherm equation
`x/m= k_(p) 1/n`
or `log "" x/m = log k + 1/n log p`
A plot of `log "" (x)/(m)` versus log p is linear with slope `= 1/n` and intercept = log k.
