Equilibrium Constant (K_c): -

A chemical equilibrium calculator helps determine the concentrations of reactants and products at equilibrium for reversible chemical reactions. It uses the equilibrium constant ($K_c$ or $K_p$) to predict the extent of a reaction, providing essential insights for chemical research and industrial applications.

How to Use the Chemical Equilibrium Calculator

Step 1: Enter Reaction Details

Provide the chemical equation and specify whether the system is in terms of concentration ($K_c$) or pressure ($K_p$).

Step 2: Input Initial Conditions

Enter initial concentrations or pressures of reactants and products, along with the equilibrium constant value.

Step 3: Perform Calculation

The calculator applies the law of mass action:

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

Where:

• $[A], [B], [C], [D]$ are the molar concentrations
• $a, b, c, d$ are the stoichiometric coefficients

Example Calculation

For the reaction:

$$N_2 + 3H_2 \rightleftharpoons 2NH_3$$

Given initial concentrations and an equilibrium constant $K_c$, the calculator solves for the equilibrium concentrations using algebraic techniques.
