Q
Q: In a binary solution of A and B, if component A has a higher vapor pressure than component B, what can be inferred about the solution?
Solution: If component A has a higher vapor pressure than component B, the solution will show positive deviation from Raoult's Law.
Steps: 6
Step 1: Understand what vapor pressure means. Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid or solid phase.
Step 2: Recognize that in a binary solution, we have two components: A and B.
Step 3: Note that if component A has a higher vapor pressure than component B, it means A evaporates more easily than B.
Step 4: Recall Raoult's Law, which states that the vapor pressure of a component in a solution is proportional to its mole fraction in the solution.
Step 5: Understand that a positive deviation from Raoult's Law occurs when the vapor pressure of the solution is higher than expected based on the individual vapor pressures of A and B.
Step 6: Conclude that since A has a higher vapor pressure, the solution will exhibit a positive deviation from Raoult's Law.
