Question

Calculate the compressibility factor for CO2, if one mole of it occupies 0.4 litre at 300 K and 40 atm. Comment on the result.

• A. 0.40, CO2 is more compressible than ideal gas
• B. 0.65, CO2 is more compressible than ideal gas
• C. 0.55, CO2 is more compressible than ideal gas
• D. 0.62, CO2 is more compressible than ideal gas

Answer 1

Answer: (B)

0.65, CO2 is more compressible than ideal gas

Answer 2

Z =$\frac{(PV)_{real}}{(PV)_{deal}}$
