Understanding Kb and Its Characteristics
The equation ΔTb = Kb * m describes the phenomenon of boiling point elevation, where Kb is the ebullioscopic constant. Let's analyze the options to understand why B and D are incorrect.
Option A: Unit of Kb
- The unit of Kb is indeed K mol–1 kg. This signifies that Kb measures the change in boiling point per molal concentration of the solute.
Option B: Dependence on Solute and Solvent
- This statement is incorrect. Kb is specific to the solvent only. It is a property of the solvent that indicates how much the boiling point will rise for a given molal concentration of a solute. The nature of the solute does not directly affect the value of Kb.
Option C: Dependence on Nature of Solvent Only
- This statement is correct. Kb is influenced solely by the solvent's chemical properties, such as its intermolecular forces and structure.
Option D: Latent Heat of Evaporation
- This is also incorrect. While a higher latent heat of evaporation often correlates with a higher boiling point, it does not necessarily mean that the value of Kb will be higher. Kb is primarily determined by the solvent's properties and may not directly relate to latent heat.
Conclusion
- Therefore, options B and D are incorrect regarding the characteristics of Kb. Understanding these distinctions is crucial for applying colligative properties in practical scenarios related to solutions.
