It is approximately 370 K and 1255 kPa.
Consider the mixing of L moles of ✓ with V moles of y, in which L+V = 1.
What is the resulting overall composition Z (you can pick a value for L. 0 <L< 1)?
Perform PT flash for that overall composition Z at the temperature-pressure condition
from part "c" (i.e., the intersection). What are the compositions of the two
equilibrium phases? Are they close to ✓ and ✓ from part c? Why, or why not?
