Q: Which of the following is NOT a condition for Raoult's Law to hold true?
Solution: Raoult's Law applies to ideal solutions, and it is not necessary for the solute to be volatile.
Steps: 4
Step 1: Understand what Raoult's Law is. It describes how the vapor pressure of a solution depends on the vapor pressures of its components and their concentrations.
Step 2: Identify the conditions for Raoult's Law to be valid. It applies to ideal solutions where the interactions between different molecules are similar to those between like molecules.
Step 3: Recognize that one of the conditions is that the solute should ideally be non-volatile, meaning it does not contribute to the vapor pressure of the solution.
Step 4: Determine which option does not fit the conditions for Raoult's Law. The correct answer will be the one that states the solute must be volatile, which is NOT a requirement.
