Equilibrium Vapour Density Formula:
From: | To: |
Definition: Equilibrium Vapour Density is the density of a vapour substance during the stages of reaction at equilibrium.
Purpose: This calculator helps determine the vapour density at equilibrium when the number of moles of products at equilibrium is half.
The calculator uses the formula:
Where:
Explanation: The formula accounts for the change in density as substances dissociate during the reaction.
Details: Understanding vapour density at equilibrium is crucial for chemical reaction analysis, industrial process design, and predicting reaction outcomes.
Tips: Enter the initial vapour density and degree of dissociation (between 0 and 1). All values must be positive numbers.
Q1: What is degree of dissociation?
A: The Degree of Dissociation is the extent of generating current carrying free ions, which are dissociated from the fraction of solute at a given concentration.
Q2: What's a typical range for degree of dissociation?
A: It typically ranges between 0 (no dissociation) and 1 (complete dissociation).
Q3: How do I measure initial vapour density?
A: Initial vapour density can be measured experimentally or calculated from molecular weight and ideal gas laws.
Q4: Why does the formula have a 2 in numerator and denominator?
A: The 2 accounts for the stoichiometry when number of moles of products at equilibrium is half.
Q5: Can I use this for any chemical reaction?
A: This formula specifically applies when the number of moles of products at equilibrium is half of the initial moles.
