Per two gram of charcoal, a gas is adsorbed by 0.1 g and 0.2 g at 10 torr and 80 torr pressure respectively. Calculate the n value in Freundlich adsorption isotherm.

Explanation

`x/m = K.P^(1//n) " (or) " (x_1)/(x_2) = ((P_1)/(P_2))^(1//n) implies (0.1)/(0.2) = ((10)/(80))^(1//n) " (or) " (1/2)^(1) = (1/2)^(3//n)`
Therefore, the value of n is 3.
