Homogeneous mixing and compressibiltiy both result from the fact that the molecules are far apart in gases. Mixting occurs because indicidual gaseous molecules have little interaction with their neighbours, assuming that no reaction taken place, the chemical identites is possible in gases because only about 0.1% of the volume of a typical gas is taken up by the molecules themselves under normal circumstances, the remaining 99.9% is empty space For H_(2) and He, force of attraction is negligible, hence, compressibility factor is

1.	Homogeneous mixing and compressibiltiy both result from the fact that the molecules are far apart in gases. Mixting occurs because indicidual gaseous molecules have little interaction with their neighbours, assuming that no reaction taken place, the chemical identites is possible in gases because only about 0.1% of the volume of a typical gas is taken up by the molecules themselves under normal circumstances, the remaining 99.9% is empty space For H_(2) and He, force of attraction is negligible, hence, compressibility factor is
Answer» `(PV)/(RT)` `(1 + (RB)/(RT))` `(1 - (a)/(RTV))` `(1 + (RT)/(Pb))` ANSWER :B
