Question 36
CHMCQ2 marksNeeds review
K value is defined as the ratio of mole fraction of a component in the vapor phase to that in the liquid phase. The K values of propane and iso-butane at 293 K are given in the table.
Pressure (kPa) | Propane | iso-Butane |
|---|---|---|
1100 | 1.8 | 0.85 |
1200 | 1.6 | 0.75 |
1300 | 1.4 | 0.65 |
1400 | 1.25 | 0.5 |
1500 | 1.1 | 0.45 |
Which one of the following is closest to the bubble point pressure (in kPa) of an equimolar mixture of propane and iso-butane at 293 K?
