Question

Which of the following is the correct set of volume calculated by ideal gas equation and vanderwaal's equation respectively for 1 mole CO₂ gas at 300K and 10 atm pressure.

• A. 2.463 L, 2.56 L
• B. 2.463 L, 2.38 L
• C. 2.463 L, 2.463 L
• D. 2.463 L, 2.5 L

Answer 1

Answer: (B)

2.463 L, 2.38 L

Answer 2

V_I =$\frac{nRT}{P}$=$\frac{1 \times 0.0821 \times 300}{10}$= 2.463 L

For CO₂, at 10 atm. Z < 1

Ž $\frac{V_{R}}{V_{I}}$ < 1

Ž V_R < V_I
