What kind of difference is observed in the amount of adsorption with the increase in temperature?

The surface area of $1 \, g$ of activated charcoal is $1000 \, m^2$. Assuming complete coverage and unimolecular adsorption,if the radius of an ammonia molecule is $10^{-8} \, cm$,then the volume of ammonia adsorbed at $STP$ on $44/7 \, g$ of carbon will be ........ $L$. $(N_A = 6 \times 10^{23})$

In Freundlich adsorption isotherm,the value of $1/n$ is

According to the Freundlich adsorption isotherm,a straight line is obtained for the plot of:

Which of the following statements is correct?

Charcoal is mixed in $500 \ mL$ of $0.5 \ M$ acetic acid solution. After some time,the concentration of the solution becomes $0.3 \ M$. Find the total number of molecules adsorbed on the surface of the charcoal.
