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

  1. Ak
  2. Bk
  3. Cn
  4. 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
