Definition: Number of Moles at Equilibrium are given when the liquid and vapour phase of the substance are in equilibrium.
Purpose: This calculator helps determine the amount of substance present at equilibrium in chemical reactions.
The calculator uses the formula:
Where:
Explanation: The initial moles are adjusted by the product of the stoichiometric coefficient and the extent of reaction.
Details: Calculating equilibrium moles is crucial for understanding reaction progress, yield prediction, and chemical process design.
Tips: Enter the initial moles, stoichiometric coefficient (can be positive or negative), and extent of reaction (must be ≥ 0).
Q1: What is the extent of reaction?
A: Extent of reaction measures the progress of a reaction and is defined as the degree to which a reaction has advanced.
Q2: How do I determine the stoichiometric coefficient?
A: It comes from the balanced chemical equation (positive for products, negative for reactants).
Q3: Can the equilibrium moles be less than initial moles?
A: Yes, if the stoichiometric coefficient is negative (for reactants).
Q4: What units are used in this calculation?
A: All quantities are in moles for consistency.
Q5: Does this work for multiple reactions?
A: This calculator handles one reaction component at a time.
