Problem 2 The attached table from Perry's Handbook gives some properties of argon. Using data

from this table estimate the following:

a) The fugacity at 300 K, 1 atm (state A).

b) The fugacity of the saturated liquid at 90 K (state B).

c) The ideal-gas Gibbs energy, Gis, of the saturated liquid at 90 K.

d) The fugacity at 50 atm, 90 K (state C).

e) Draw a qualitative P V graph and show the states A, B and C of the previous parts.

At atmospheric pressure and 300 K, the properties of Argon are: p = 0.0406 mol/L, H =

13919 J/mol, S = 154.82 J/mol K. (see Perry and Chilton, Chemical Engineer's Handbook,

Fifth Edition, McGraw-Hill, New York, 1973 p. 3-159.)
