A gas at $350\mathrm{ }\mathrm{K}$ and $15$ bar has a molar volume $20$ per cent smaller than that for an ideal gas under the same conditions. The correct option about the gas, and its compressibility factor $\left(\mathrm{Z}\right)$ is

• A

  $\mathrm{Z}>1$ and repulsive forces are dominant.
• B

  $\mathrm{Z}>1$ and attractive forces are dominant.
• Correct answer
  C

  $\mathrm{Z}<1$ and attractive forces are dominant.
• D

  $\mathrm{Z}<1$ and repulsive forces are dominant.

Hence, the correct answer is option: 'C'.
