Question

A certain gas obeys the van der Waals equation with a = 0.50 m6 Pa mol-2
. Its volume is found to
be 0.5 dm3mol-1 at 273 K and 3.0 MPa. From this information, calculate the van der Waals constant
b. Calculate the compressibility factor, Z, and state whether the gas exhibits ideal behaviour,
negative deviation or positive deviation from ideal behaviour.

Answer 1

b=$4.61×10 ^{-3}m^3 mol$
