Quizplus · Accepted Answer

The boiling temperature of the liquid formed from the condensation of the vapor above a boiling solution can be estimated using Raoult's Law, which states that the vapor pressure of a solution is directly proportional to the mole fraction of the solvent times the vapor pressure of the pure solvent. Given the solution is 0.70 X_A and 0.30 X_B, without specific boiling points or vapor pressures for substances A and B, we can infer that the boiling temperature of the solution would be between the boiling points of pure A and pure B. Assuming A has a lower boiling point and B has a higher one, the temperature of 55°C is a reasonable approximation, suggesting it is closer to the boiling point of A but elevated due to the presence of B.
