Water is compressed isothermally from 450 K and 1x105 Pa until the system is completely liquid.

The following data is provided:

Van der Waals EOS coefficients: a: 0.5536 J.m3.mol-2 b: 3.049 x 10-5 m3.mol-1

Calculate the total change in entropy for this process by adding Use the Van der Waals EOS, NOT PITZER:

a) The entropy change for isothermal compression up to the point of phase change.(Note: ideal gas in initial conditions and Z=0.97 in saturation conditions at 450K)

b) The entropy of phase change. You can use the result from normal conditions.
