Question
Calculate the compressibility factor for $CO_2$ if one mole of it occupies $0.4\text{ litre}$ at $300\text{ K}$ and $40\text{ atm}$. Comment on the result.
Answer: B
💡 Solution & Explanation
$Z = PV/nRT = (40 \times 0.4) / (1 \times 0.0821 \times 300) = 16 / 24.63 = 0.65$. Since $Z < 1$, attractive forces dominate, making it more compressible than an ideal gas.
