Calculate the second virial coefficient of ammonia from its van der Waals constants.?
Answer:
The second virial coefficient B and the van der Waals parameters a,b are related by:
B = b - a /(R·T)
( R universal gas constant , T absolute temperature in kelvins)
The van der Waals parameters for ammonia are
a = 4.225 L²bar/mol²
b = 0.03707 L/mol
The rest is cake. Just specify a temperature and calculate B from the equation above.
ahhh...thermo.good luck!
