2. Let us consider CO2 (44 g/mol, tripple point: -56.6 C and 5.1 atm) under different conditions. (a) CO2 has a concentration of 400 ppm in air, what is its fugacity? (b) The fugacity of the saturated CO2 vapor at 5 C and 39 atm using the Pitzer correlation. For relevant thermodynamic properties, please refer to Table C on page 735 of Textbook. (c)The fugacity of the saturated CO2 liquid at 5 C and 39 atm using Peng-Robinson EOS. Hint: cubic EOS's are more reliable for vapors gases
