22Jan19.Quiz-u1m2-quizi-saying-goodbye-u1m1.pdf (1 page) Q Search 1. Using the vapor pressure curves given, what are the normal boiling points (at 1.0 atm) A) A is -30°C and B is zero B) A and B are both -30 °C 0 Aand Bare both 47 °C 2. At what temperatures and pressure can A and B be separated? Using the image from Question 1 A) 1 atm and 10 C B 0.3 atm and 10 °C C 0.1 atm and 10 °C 3. What phases of A, B, C and D are present at 1atm and 25C? A gas: A, B, C, D Liquid: none ) gas: A, B, C Liquid: D gas:none Liquid: A B c.o D) gas: D Liquid: A, B, C 4. At which temperature and pressure can A be separated from B, C and D? A 1 atm and S0C B 1 atm and 30C C 1 atm and 10C D 1 atm and-10C

Explanation / Answer

1. The boiling point is where the vapor pressure of the gas equals the atmospheric pressure, so when the vapor pressure is 1 atm I can see on the graph that A and B have the same vapor pressure , therefore A is not possible

Right answer is c, approximattely 47C

For the second question please provide a better image it is hard to read the vapor pressure label, i am not sure if the middle value is a 0.5 or 0.3 ....
