Q: Which of the following is a limitation of Raoult's Law?
Solution: Raoult's Law is primarily valid for ideal solutions, where the interactions between molecules are similar to those in the pure components.
Steps: 4
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 and their mole fractions.
Step 2: Recognize that Raoult's Law applies best to ideal solutions. An ideal solution is one where the molecules interact similarly to how they do in their pure forms.
Step 3: Identify the limitation: Raoult's Law does not work well for non-ideal solutions, where the interactions between different molecules are significantly different from those in the pure substances.
Step 4: Conclude that the main limitation of Raoult's Law is its applicability only to ideal solutions.
