nounpl: equilibrium concentrations
concentração de equilíbrio
1. The concentration of a substance in a chemical system at equilibrium, where the rate of forward reaction equals the rate of reverse reaction, resulting in no net change in concentrations over time
The equilibrium concentration of the reactants and products remained constant throughout the experiment.
A concentração de equilíbrio dos reagentes e produtos permaneceu constante durante todo o experimento.
2. The specific amount of a dissolved substance per unit volume of solution when a reversible reaction has reached its equilibrium state
We calculated the equilibrium concentration using the equilibrium constant expression.
Calculamos a concentração de equilíbrio usando a expressão da constante de equilíbrio.
This is a technical term primarily used in academic and professional chemistry contexts in both Brazil and the United States. It is fundamental to understanding chemical reactions taught in high school and university chemistry courses. The concept is universally understood among chemistry professionals across English and Portuguese-speaking countries.
