Understanding Raoult's Law
Raoult's Law is a fundamental principle in physical chemistry that provides insights into the behavior of vapor pressure in solutions.
Definition of Raoult's Law
- Raoult's Law states that the partial vapor pressure of each component in a solution is equal to the vapor pressure of the pure component multiplied by its mole fraction in the solution.
Mathematical Representation
- Mathematically, it can be expressed as:
\[ P_i = P_i^0 \times x_i \]
Where:
- \( P_i \) = partial vapor pressure of component \( i \)
- \( P_i^0 \) = vapor pressure of the pure component \( i \)
- \( x_i \) = mole fraction of component \( i \) in the solution
Implications of Raoult's Law
- This law implies that as the concentration of a non-volatile solute increases, the mole fraction of the solvent decreases, leading to a decrease in the overall vapor pressure of the solution.
- It is particularly applicable to ideal solutions, where interactions between different molecules are similar to those within pure substances.
Significance in Chemistry
- Raoult's Law helps in predicting how the presence of solutes affects the vapor pressure of solvents, which is critical in applications such as distillation and understanding colligative properties.
Conclusion
- Therefore, option 'C' correctly describes Raoult's Law, as it relates the total vapor pressure of a solution to the mole fractions of its components, allowing for a better understanding of vapor behavior in mixtures.
