Question
Problem 1. Answer the following questions. A) Explain dew point and bubble point curves. B) What assumptions do we make for Raoult's Law? What are the differences between Raoult's Law and Modified Raoult's Law? C) Sketch a P-xyz diagram for Raoult's Law. Are dew point and bubble point curves linear or non-linear? Explain why! D) The total pressure of a non-ideal mixture calculated from Modified Raoult's may be greater (positive deviation) or less (negative deviation) than that predicted by Raoult's Law. Explain what this positive or negative deviation implies? Explain the interactions of unlike and like molecules in the ideal and real mixtures! Provide some examples! E) Explain what the azeotropic point means? What will be the activity coefficients at the azeotropic point?
