Positive deviation from ideal behaviour takes place because of

Options

  1. Amolecular interaction between atoms and P V n R > 1
  2. Bmolecular interaction between atoms and P V n R T < 1
  3. Cfinite size of atoms and P V n R T > 1
  4. Dfinite size of atoms and P V n R T < 1

Correct answer

C. finite size of atoms and P V n R T > 1

Step-by-step solution

For positive deviation P V n R T > 1 P V = n R T + n P b P V / n R T = 1 + P b / R T P V / n R T > 1 .
