Q: For a solution to obey Raoult's Law, the interactions between solute and solvent must be:
Solution: For a solution to obey Raoult's Law, the interactions between solute and solvent must be similar to those in the pure components.
Steps: 5
Step 1: Understand what Raoult's Law states. It says that the vapor pressure of a solution is related to the vapor pressures of its components in their pure states.
Step 2: Identify the components of the solution: the solute (the substance being dissolved) and the solvent (the substance doing the dissolving).
Step 3: Recognize that for Raoult's Law to apply, the interactions between the solute and solvent must be similar to the interactions between the molecules in the pure solvent and the pure solute.
Step 4: This means that if the solute and solvent interact in a similar way as they do with themselves, the solution will behave ideally and follow Raoult's Law.
Step 5: Conclude that similar interactions lead to predictable changes in vapor pressure, which is the essence of Raoult's Law.
