Respuesta :

The answer is P1 and P4- (The last option) because solute breaks down into same particles.

Explanation:

[tex]P_A=X_AP^o_A[/tex][tex]\begin{gathered} \text{where P}_AisthevapourpressureofcomponentA,X_Amolefraction,P^0_A \\ is\text{ the vapour pressure of pure A} \end{gathered}[/tex]

Therefore PoA of ethanol component A and B will be the same.
