Van der Waals equation of state is (P+(n2a)/V2)(V-nb)=nRT where a and b are temperature-independent parameters that have different values for each gas. For CO2, a=0.3640 Pa m6/mol2 and b=4.267*10-5 m3/mol a) Write this equation as a cubic equation in V

The ideal gas law describes the relationship among the volume of an ideal gas (V), its pressure (P), its absolute temperature (T), and number of moles (n): PV=nRT Under standard conditions, the ideal gas law does a good job of approximating these properties for any gas. However, the ideal gas law does not account for all the properties of real gases such as intermolecular attraction and molecular volume, which become more pronounced at low temperatures and high pressures. The van...

Explain (each step) and Answer please
One empirical equations of state of a real gas is: van der Waals: P = RT/V_m - b - a/V_m^2 Evaluate (partial differential s/partial differential V)_T, for a van der Waals and a perfect gas. (A Maxwell relation might help!) For an isothermal expansion, for which kind of gas (vdW or perfect gas) will delta S be greatest? Explain your conclusion.

‡ Here we explore the van der Waals equation of state in more detail. (a) Repeat Derivation 2.2 for a gas that obeys the equation of state p = nRT/(V − nb), which is appropriate when molecular repulsions are important. Does the gas do more or less work than a perfect gas for the same change of volume? (b) Now repeat the preceding exercise for a gas that obeys the equation of state p = nRT/V − n2a/V2, which is...
