The adsorption of a gas at a metal surface is called occlusion. The extent of gas adsorbed at metal surface at a certain temperature depends on pressure as
`(x)/(m)=K.P^(1//n)`
where K and n are constant for a particular combination of gas and metal at fixed temperature and `(x)/(m)`is the mass of gas adsorbed per unit mass of metal .For `H_(2)` gas adsorbing at Pt-surface, the following graph is obtained.

The correct values of K and n are respectively.
