JEE Main & Advanced Chemistry States of Matter Question Bank Ideal gas equation and Related gas laws

  • question_answer The compressibility of a gas is less than unity at STP. Therefore [IIT 2000]

    A)                 \[{{V}_{m}}>22.4\]litres               

    B)                 \[{{V}_{m}}<22.4\]litres

    C)                 \[{{V}_{m}}=22.4\]litres               

    D)                 \[{{V}_{m}}=44.8\]litres

    Correct Answer: B

    Solution :

               Compressibility = \[\frac{PV}{nRT}<1\] at STP (as given)            \[\left. \begin{align}   & nRT>PV \\  & N\times 0.0821\times 273>1{{V}_{m}} \\  & 22.41\ litres>{{V}_{m}} \\ \end{align} \right\}\begin{matrix}    R=\text{ }0.821  \\    T=\text{ }{{273}^{o}}K  \\    P\text{ }=\text{ }1  \\ \end{matrix}\]      n = 1
