Enter the molar concentration and coefficients of the 4 substances into the calculator. The calculator will evaluate and display the equilibrium constant of those substances.
Equilibrium Constant Formula
The following formula can be used to calculate the equilibrium constant of a solution.
K = ([C]c * [D]d)/([B]b * [A]a)
- Where K is the equilibrium constant
- [A,B,C,D] are the molar concentrations of those substances
- a,b,c,d are the coefficients of each substance
Equilibrium Constant Definition
An equilibrium constant is a constant used to describe when a solution will be at equilibrium.
Equilibrium Constant Example
How to calculate equilibrium constant
