QJEEM21Ch4d4d: JEE Main 2021 Chemistry - Class 12 JEEM21Ch4d4d Solution: CO 2 gas adsorbs on charcoal following Freundlich adsorption…

CO2 gas adsorbs on charcoal following Freundlich adsorption isotherm. For a given amount of charcoal, the mass of CO2 adsorbed becomes 64 times when the pressure of CO2 is doubled. The value of n in the Freundlich isotherm equation is ____________ ×\times 10 −- 2. (Round off to the Nearest Integer)

Step-by-Step Verified Solution

Freundlich isotherm;

xm=k.p1n{x \over m} = k.{p^{{1 \over n}}}

Substituting values ;

(641)=(2)1n⇒n=16=0.166\left( {{{64} \over 1}} \right) = {\left( 2 \right)^{{1 \over n}}} \Rightarrow n = {1 \over 6} = 0.166

≅17×10−2\cong 17 \times {10^{ - 2}}
