Question 95
XE-EMCQ2 marksNeeds review
The van der Waals equation of state is given as,
where p in bar, v in m³/kmol and T is in K.
For air, the constants, a and b, are 1.368 bar.(m³/kmol)² and 0.0367 m³/kmol, respectively. Air is contained in a system at 160 K and 0.08 m³/kmol. If p₁ is the pressure calculated using ideal gas equation of state and p₂ is pressure calculated using van der Waals equation of state, then p₁/p₂ is equal to
