Question

$P_A$ and $P_B$ are the vapour pressure of pure liquid components, A and B, respectively of an ideal binary solution. If $X_A$ represents the mole fraction of component A, the total pressure of the solution will be.
(a) $P_A + X_A (P_B - P_A)$
(b) $P_A + X_A (P_A - P_B)$
(c) $P_B + X_A (P_B - P_A)$
(d) $P_B + X_A (P_A - P_B)$

Answer 1

option d is correct

i hope it is clear
