Solutions - tiny doubt in a question
So here's a problem from the chapter solutions. I want to solve it using Ya/Yb = (Xa/Xb)(P0A/P0B)...
I've reached up to this eqn: P0bxy= Pa - Pay - Pax+ Paxy. What I don't understand is where did that x term go in the original expression of Pa. Is it cuz we're taking x = 0 as it is an exp for Pa? I guess that is it but would like to confirm.

to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.okay sir. i just want to know if the x term has to be ignored cuz we're looking at Pa. i was able to solve the problem

i am not able to figure out what you mean by this.
sorry about the weird lines but did the same thing I said in the voice note
the ans is 110
p0b
yea my bad, i took x to be mole fraction of A :D You can figure it out, fix the equation above.
write xa = 1-xb and retain things
you will get PoA to be 235
235-125 = PoB ie 110
okay yes sir
thank you
