What is the value of the intercept on the $y$-axis when $\log \frac{x}{m}$ is plotted against $\log P$ in the Freundlich isotherm?

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

Amongst the following statements regarding adsorption,those that are valid are :
$(a)$ $\Delta H$ becomes less negative as adsorption proceeds.
$(b)$ On a given adsorbent,ammonia is adsorbed more than nitrogen gas.
$(c)$ On adsorption,the residual force acting along the surface of the adsorbent increases.
$(d)$ With increase in temperature,the equilibrium concentration of adsorbate increases.

Which of the following statements is not correct in respect of chemisorption?

If the adsorbate is held on a surface by weak Van der Waals forces,the adsorption process is called:

Which of the following conditions is favorable for $Van \ der \ Waals$ adsorption?
