1. What is the Equilibrium Constant?

The equilibrium constant (K_eq) quantifies the position of equilibrium in a chemical reaction. It represents the ratio of product concentrations to reactant concentrations, each raised to the power of their stoichiometric coefficients.

2. How Does the Calculator Work?

The calculator uses the equilibrium constant formula:

\[ K_{eq} = \frac{[C]^c [D]^d}{[A]^a [B]^b} \]

Where:

\( [A], [B] \) — Concentrations of reactants (M)
\( [C], [D] \) — Concentrations of products (M)
\( a, b \) — Stoichiometric coefficients for reactants
\( c, d \) — Stoichiometric coefficients for products

Explanation: The equilibrium constant provides information about the extent of a reaction at equilibrium. A large K_eq indicates products are favored, while a small K_eq indicates reactants are favored.

3. Importance of Keq Calculation

Details: Calculating the equilibrium constant is essential for predicting reaction direction, understanding chemical equilibria, and designing industrial chemical processes.

4. Using the Calculator

Tips: Enter all concentrations in molarity (M) and stoichiometric coefficients as positive numbers. Ensure all values are valid (concentrations ≥ 0, exponents ≥ 0).

5. Frequently Asked Questions (FAQ)

Q1: What does Keq > 1 indicate?
A: Keq > 1 indicates that products are favored at equilibrium, meaning the reaction proceeds predominantly toward product formation.

Q2: What does Keq < 1 indicate?
A: Keq < 1 indicates that reactants are favored at equilibrium, meaning the reaction proceeds predominantly toward reactant formation.

Q3: Is Keq affected by temperature?
A: Yes, the equilibrium constant is temperature-dependent. Changes in temperature can shift the equilibrium position.

Q4: What are the units of Keq?
A: Keq is dimensionless for reactions where the sum of product coefficients equals the sum of reactant coefficients. Otherwise, it has units based on concentration differences.

Q5: Can Keq be negative?
A: No, equilibrium constants are always positive values since they represent ratios of concentrations raised to positive exponents.
