Hi there!(adsbygoogle = window.adsbygoogle || []).push({});

I'm having a little problem here and hopefully someone here can help.

I am studying for a Physical Chemistry exam and there is an exercise here I just can't solve. It asks to find the ideal and the real parcial pressure of A, given xA, yA and pt ---- xA being the molar fraction of A in the liquid phase and yA the molar fraction of A in the gaseous phase.

I was thinking of using Raoult's law and Dalton's law, but don't they both give the ideal values of the partial pressure?? How can I get the real values?

Thanks! :)
