If x gram of gas is adsorbed by m gram of adsorbent at pressure P the plot of x ~m versus P is linear. The slope of the plot is: ( m and k are constants and n>1 )

Options

  1. Ak
  2. B1 n
  3. C2 k
  4. Dn

Correct answer

B. 1 n

Step-by-step solution

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