Ethane is held at 300 K and 200 atm. Solve for the molar volume under these conditions using (i) ideal gas, (ii) the van der Waals equation of state, and (iii) the Soave-Redlich-Kwong equation of state. What is the percent error involved in the result of each equation if the experimental value is 0.071 L/mol? The critical pressure and critical temperature of ethane is 48.80 bar and 305.42K.
