Adsorption of a gas follows Freundlich adsorption isotherm. In the given plot,xis the mass of the gas adsorbed on massmof the adsorbent at pressure (P). ifxmP(1/y)find the magnitude ofyis ------.

Answer:
2.00
Solution:

According to Freundlich adsorption isotherm,
xm=K×P1/n
logxm=logK+1nlogP
m=1n=24=12n=2
So,xm=K×P1/2
Therefore, value of'y'is2.
