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$-$2. (Round off to the Nearest Integer)
Answer (integer)
17
Solution
Freundlich isotherm;<br><br>${x \over m} = k.{p^{{1 \over n}}}$<br><br>Substituting values ;<br><br>$$\left( {{{64} \over 1}} \right) = {\left( 2 \right)^{{1 \over n}}} \Rightarrow n = {1 \over 6} = 0.166$$<br><br>$\cong 17 \times {10^{ - 2}}$
