Definition: This calculator determines the equilibrium constant (Kχ) for a chemical reaction based on the degree of dissociation (α) of the reactants.
Purpose: It helps chemists and chemical engineers understand the extent of dissociation at equilibrium for reactions involving gases or solutions.
The calculator uses the formula:
Where:
Explanation: The formula relates the equilibrium constant to the fraction of molecules that dissociate at equilibrium.
Details: Knowing the equilibrium constant helps predict reaction direction, extent of reaction, and optimize reaction conditions.
Tips: Enter the degree of dissociation (α) as a value between 0 (no dissociation) and 1 (complete dissociation).
Q1: What is the degree of dissociation?
A: It's the fraction of reactant molecules that dissociate into products at equilibrium.
Q2: What range of values can α have?
A: α must be between 0 (no dissociation) and 1 (complete dissociation).
Q3: When does this formula apply?
A: This specific formula applies to simple dissociation reactions where one molecule dissociates into two particles.
Q4: How does temperature affect Kχ?
A: The equilibrium constant is temperature-dependent. This calculator assumes constant temperature.
Q5: What are the units of Kχ?
A: Kχ is dimensionless when expressed in terms of mole fractions.
