Among the gases a, b, c, d, e and f, the gases that show only positive deviation from ideal behavior at all pressures in the graph are

  1. b, c only
  2. b, c, a only
  3. d, e only
  4. d, e, f only

Solution

When Z < 1, it is a negative deviation. It shows that the gas is more compressible than expected from ideal behaviour. When Z > 1, it is a positive deviation. It shows that the gas is less compressible than expected from ideal behaviour. Only b and c gases showing exclusive positive deviation.
