Question

Calculate the compressibility factor for $CO_{2}$, if one mole of it occupies $0.4$ litre at $300\, K$ and $40\, atm$. Comment on the result:

• A. $0.40, CO_{2}$ is more compressible than ideal gas
• B. $0.65, CO_{2}$ is more compressible than ideal gas
• C. $0.55,CO_{2}$ is more compressible than ideal gas
• D. $0.62, CO_{2}$ is more compressible than ideal gas

Answer 1

Answer: (B)

$Z=\frac{PV}{RT}$
$\Rightarrow \frac{40\times0.4}{300\times0.082}$
$Z=0.65$
