The charcoal maintained at $100 \ K$ absorbs

Wood charcoal is used to decolourise sugar because it

Arrange the gases $H_2, CH_4, CO_2,$ and $NH_3$ in the order of their volume adsorbed on $1 \ g$ of charcoal at $288 \ K$.

The decomposition of gaseous $H_2$ adsorbed on a metal surface like tungsten is a reaction of which order?

Which of the following gases is readily adsorbed by solid adsorbent?

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.
