Please answer all the following questions I'll give thumbs up.

Question 1 (1 point) What is assumed when using the ideal gas model? y; = 0 Ox; = 0 X Yi = 1 0; = 1 Question 2 (1 point) What equation(s) is(are) used when we assume the ideal gas model? fi = yifi Ptot Yi - f = x;P,sat = P - i fi = x;yiPysat = f = getot Question 3 (1 point) The Redlich-Kister model is: empirical derived from theory neither of the other choices both of the other choices Question 4 (1 point) The relative volatility, Qij, is less than 1 on one side of an azeotrope and greater than one on the other. True False Question 5 (1 point) Saved As xi goes to 0, Y; becomes: 1 infinity 0 Question 6 (1 point) Saved As xi goes to 1, Y; becomes: infinity 1 Question 7 (1 point) The two-parameter Margules equation cannot be linearized to plot experimental data in a form that leads to obtaining the constants through a slope and an intercept. True False Question 8 (1 point) The Gibbs-Duhem equation for a binary system states that: a in 72 21 a ln 71 ; +22 ( =0 ari True False
