Surface Chemistry Question 9

Question 9 - 01 February - Shift 2

In figure, a straight line is given for Freundrich Adsorption $(y=3 x+2.505)$. The value of $\frac{1}{n}$ and $\log K$ are respectively.

(1) 0.3 and $\log 2.505$

(2) 0.3 and 0.7033

(3) 3 and 2.505

(4) 3 and 0.7033

Show Answer

Answer: (3)

Solution:

$\frac{X}{m}=Kp^{1 / n}$

$\log \frac{x}{m}=\log k+\frac{1}{n} \log P$

$.Y=3 x+2.505, \frac{1}{n}=3, \log K=2.505)$
