The equation for Freundlich adsorption isotherm is a) x m = k p 1 n b) ( l n x ) = l n ( m k ) + 1 n l n p c) x m = k p − n d) Only a and b Options: A . &nbspa B . &nbspb C . &nbspc D . &nbspd

Answer: Option D : D The equation is: x m = k p 1 n ⇒ l n ( x m ) = l n k + ( 1 n ) l n p ⇒ l n x − l n m k + ( 1 n ) l n p l n x = l n m + l n k + ( 1 n ) l n p ⇒ l n x = l n m k + ( 1 n ) l n p

The equation for Freundlich adsorption isotherm is a) xm=kp1n b) (ln

Question

The equation for Freundlich adsorption isotherm is
a)

\frac{x}{m} = k p^{\frac{1}{n}}

(l n x) = l n (m k) + \frac{1}{n} l n p

\frac{x}{m} = k p^{- n}

d) Only a and b

Options:

A . a

B . b

C . c

D . d

Answer: Option D
:
D
The equation is:

\frac{x}{m} = k p^{\frac{1}{n}} \Rightarrow l n (\frac{x}{m}) = l n k + (\frac{1}{n}) l n p \Rightarrow l n x - l n m k + (\frac{1}{n}) l n p

l n x = l n m + l n k + (\frac{1}{n}) l n p \Rightarrow l n x = l n m k + (\frac{1}{n}) l n p
