NEET Practice Questions (MCQs) with Answers & Solutions

Which of the following statements is / are correct ? A) At high prssure, all real gases are less compressible than ideal gas. B)$ H_2 $ he gases are more compressible than ideal gas for all values of pressure C) $ compressiblity factor z = ( PV \over nRT) is less than 1 for all real gases at low pressure except H_2 $ and He D)The compressibility factor z of real gases are quite independent of temperature therefore z is not effected with change in temperature.

A gas Undergoes dissociation as $M_{ 4(q ) } \rightarrow 4M (g) $ in a closed rigid container having volume 22.4L at 273K If the initialmoles of $M_4$ taken befor dissoliciation is 1 then. The total pressure (in attm) after 50% completion of the reaction assuning ideal behaviour is

A gas Undergoes dissociation as $M_{ 4(q ) } \rightarrow 4M (g) $ in a closed rigid container having volume 22.4L at 273K If the initialmoles of $M_4$ taken befor dissoliciation is 1 then. If the gases are not ideal at the begining total pressure observed is less than 1 atm then
