Overview

The thermodynamics of binary systems is a crucial area of study that examines how two-component mixtures behave under various conditions. Understanding phase equilibrium, Gibbs free energy, and laws like Raoult's Law allows scientists and engineers to predict how mixtures will react in real-world ap...

Key Terms

Binary System
A mixture containing two components.

Example: Water and ethanol form a binary system.

Phase Equilibrium
A state where the phases of a system do not change over time.

Example: Liquid and vapor phases of water at boiling point.

Gibbs Free Energy
A thermodynamic potential that measures the maximum reversible work.

Example: A reaction is spontaneous if Gibbs free energy decreases.

Raoult's Law
States that the vapor pressure of a component in a mixture is proportional to its mole fraction.

Example: In a solution, the more solute, the lower the vapor pressure.

Clausius-Clapeyron Equation
Describes the relationship between pressure and temperature during phase changes.

Example: Used to calculate the boiling point of a liquid at different pressures.

Ideal Solution
A solution that follows Raoult's Law perfectly.

Example: A mixture of benzene and toluene is often considered ideal.
