Find changes in isothermal process for u h and s for a gas

Question

Problem

1. Find changes in an isothermal process for u, h, and s for a gas with an EOS as P(v - b) = RT.

2. Find changes in internal energy, enthalpy, and entropy for an isothermal process in a gas obeying the van der Waals EOS.

3. Consider the following EOS, expressed in terms of reduced pressure and temperature: Z = 1 + (P_r/14T_r)[1 - 6T_r ^-2]. What does this predict for the reduced Boyle temperature?

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
