Chemistry question

A gas at 350 K and 15 bar has a molar volume 20% smaller than that for an ideal gas under the same conditions. The correct statement about the gas and its compressibility factor (ZZ) is:

  1. A.Z>1Z>1 and attractive forces are dominant
  2. B.Z>1Z>1 and repulsive forces are dominant
  3. C.Z<1Z<1 and attractive forces are dominant✓
  4. D.Z<1Z<1 and repulsive forces are dominant

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
