    Answer is 2 plz mention reason

    We know that, Z = pV/nRT
    For an ideal gas Z=1
    At high pressure value of Z increases because repulsion b/w molecules gives a noticable effect making molar volume Vm of the real gas greater than the molar volume of the ideal gas (Vm (ideal gas ) = RT/p ) causing Z to exceed 1.

    When pressures are lower, attractive forces dominate making Z
    So, if we increase the molar volume Vm of a gas, the pressure decreases, as a result attractive forces dominate making Z

    So, the answer is Vm>22.4L.
