alleryRaoult's law for ideal solution states vapor pressure of solvent:
AP_A = P°_A × x_A (mole fraction in solution)
BP_A = x_B × P°_A
CP_A = K_H × x_A
DP_A = P°_A always
Answer & Solution
Correct answer: A. P_A = P°_A × x_A (mole fraction in solution)
**Raoult's law:** vapor pressure of each component in ideal solution = its pure-state vapor pressure × mole fraction.
P_total = P°_A x_A + P°_B x_B.
Foundation of distillation.
