2.71 Consider the following mixture that is coming out of a methanol reactor. CO, 100; H2, 200; methanol, 100 kmol/h. The gas is at 100 atm and 300°C. Compute the specific volume using (a) ideal gas law (b) Redlich-Kwong equation of state (c) Redlich-Kwong-Soave equation of state. Give reasons why the ideal gas or Redlich-Kwong equations of state are not expected to be valid choices. The acentric factors for the RK-Soave method are: CO, 0.049; H2, -0.22; methanol, 0.559. Where did you get the other data you needed? How do the three answers compare? Is the gas ideal or not? Comment.
