'a' and 'b' are van der Waals' constants for gases. Chlorine is more easily liquefied than ethane because

Options

  1. Aa and b for Cl ₂ < a and b for C ₂ H ₆
  2. Ba for Cl ₂ b for C ₂ H ₆
  3. Ca for Cl ₂> a for C ₂ H ₆ but b for Cl ₂ < b for C ₂ H ₆
  4. Da and b for Cl ₂>a and b for C ₂ H ₆

Correct answer

C. a for Cl ₂> a for C ₂ H ₆ but b for Cl ₂ < b for C ₂ H ₆

Step-by-step solution

ease of liquefaction a b for ethane a=5.49, b=0.0638 for Cl ₂ a =6.49, ~b =0.0562
