1. What is Volume of Equilibrium Mixture?

Definition: This calculator determines the volume of substances A and B at equilibrium stage during a chemical reaction.

Purpose: It helps chemists and chemical engineers calculate the equilibrium volume based on dissociation degree, product moles, and initial volume.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_{eq} \) — Volume at equilibrium (cubic meters)
• \( \alpha \) — Degree of dissociation (0 to 1)
• \( y \) — Number of moles of products at equilibrium
• \( V \) — Initial volume of solution (cubic meters)

Explanation: The formula accounts for volume changes due to dissociation and the number of product moles formed at equilibrium.

3. Importance of Equilibrium Volume Calculation

Details: Accurate equilibrium volume calculations are crucial for reactor design, process optimization, and understanding reaction thermodynamics.

4. Using the Calculator

Tips: Enter the degree of dissociation (0-1), number of product moles at equilibrium (≥1), and initial volume (>0). All values must be valid.

5. Frequently Asked Questions (FAQ)

Q1: What is degree of dissociation?
A: It's the fraction of reactant molecules that dissociate into products, ranging from 0 (no dissociation) to 1 (complete dissociation).

Q2: How do I determine the number of product moles?
A: This comes from the stoichiometry of your balanced chemical equation at equilibrium.

Q3: Why does volume change at equilibrium?
A: Volume changes because dissociation often produces more particles, which may occupy different volumes than the original substances.

Q4: What units should I use?
A: Use consistent units - degree of dissociation is unitless, moles is unitless count, and volume should be in cubic meters.

Q5: Can this be used for gas-phase reactions?
A: Yes, but ensure your volume measurements account for gas expansion/compression under reaction conditions.
