(10 points) Where is the fugacity larger point A or point B? Why? (The plot shows an isotherm. On the isotherm Psat = 0.7). Indicate in the plot the location of the critical point and also describe the states of points A and B (i.e., saturated liquid or vapor, metastable liquid or vapor, stable liquid or vapor) 1 0.9 0.8 - A psat 0.7 0.6 - OD B 0.5 0.4 0 1 2 3 5
