3. Please answer each question to reflect our discussions in class. a. The figure to the right is a PT diagram for a pure substance. In a color other than

black or gray, please label the diagram to show the region or point on the diagram that represents(i) solid, (ii) liquid, (iii) vapor, (ir) supercritical, (v) triple point, and (vi) critical point. b. Please consider a sample of air at 392 °C and1.88 bar. Based on Simple Corresponding States Theory, would we expect a significant error if the air were modeled as an Ideal Gas? Please use appropriate calculations and a sentence or t Please refer to the data below while addressing Parts c, d, and e. Pure CCl4 (1)and pure CH6 (2) were examined at 25 °C with the following results: c. Please determine the Ideal Molar Volume, iID (in em/mole) for a solution ofCC4 (1) and C6H6 (2) at 25 °C and x = 0.3. d. The measured molar volume of a solution of CCl (1) and C6H6 (2) at 25 °Cand x1 = 0.3 is 96.60 cm/mole. Please determine the excess molar volume,(in cm/mole) of the solution at 25 C and x = 0.3. e. Based on the value of , what (if anything) can one say about the 1-2 or 2-1interactions relative to 1-1 and 2-2 interactions? Please explain in one or twosentences.
