For adsorption of a gas on a solid, the plot of log x / m vs log P is linear with slope equal to ( n being whole number)
Options
- Ak
- Bk
- Cn
- D1 n
Correct answer
D. 1 n
Step-by-step solution
According to Freundlich adsorption isotherm, at intermediate pressure, extent of adsorption x m =k P ^ 1 / n or x m = k+ 1 n P plot of x m vs log P is linear with slope = 1 n
