KEquilibrium Calculator

Calculate the concentrations at the equilibrium of a reversible chemical reaction using this app! Simply enter in the chemical equation, enter the Keq value, and then enter in the initial concentrations of each compound. This app can also backward calculate for the Keq value by simply leaving the Keq field blank. This app includes the main steps for all calculations.

Equation Syntax:
- Use capitalizations to indicate a separate molecule
- Use = to indicate a reversible reaction
- Use + to separate compounds
Eg. PCl3 + NO2 = POCl3 + NO

Features:
- Tutorials quizzes which teach how to read values from a question
- Can check if your reaction equation is balanced
- Solves for the concentrations of compounds at equilibrium
- Solves for the Keq constant
- Shows main steps in calculations
- Supports polynomials up to degree 3 in Keq formulas
- Screen fitting horizontal view mode for wider table display
- Clean and elegant design for both light and dark mode
