Vapor Pressure Formula:
From: | To: |
Definition: This calculator determines the vapor pressure of one component in a mixture of immiscible liquids based on the known vapor pressure of the other component.
Purpose: It helps in understanding and predicting the behavior of immiscible liquid mixtures in chemical processes and thermodynamics.
The calculator uses the formula:
Where:
Explanation: The formula relates the vapor pressures of two immiscible liquids through their molecular masses and weights in the mixture.
Details: Accurate vapor pressure calculations are crucial for distillation processes, phase equilibrium studies, and chemical engineering applications involving immiscible liquids.
Tips: Enter all required values in consistent units (kg for weights, kg/mol for molecular masses, Pa for pressures). All values must be positive numbers.
Q1: What are immiscible liquids?
A: Immiscible liquids are those that don't mix to form a homogeneous solution (like oil and water).
Q2: Why does this formula work for immiscible liquids?
A: For immiscible liquids, each component exerts its own vapor pressure independently of the other.
Q3: What units should I use for molecular mass?
A: Use kg/mol for consistency with SI units, but you can use g/mol if you adjust other units accordingly.
Q4: Can this be used for miscible liquids?
A: No, this formula is specifically for immiscible liquid mixtures.
Q5: How accurate is this calculation?
A: It provides theoretical values assuming ideal behavior and complete immiscibility.
