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.

Compare the enthalpy of chemical adsorption with physical adsorption.

Which of the following statements is $NOT$ true about absorption?

When $\left( \frac{m}{x} \right)$ is plotted against $\frac{1}{p}$ for the equation $\frac{x}{m} = \frac{ap}{1 + bp}$,we get a straight line. What are the slope and intercept of this line?
