<h3>What are equilibrium reactions?</h3>
An equilibrium reaction is a chemical reaction process in which the reactants remain in a steady and stable condition both previously(reactant) and after the reaction is completed(product).
A reaction is considered to be at thermodynamic equilibrium when a reaction meets all three categories of equilibrium;
- Equilibrium of temperature
- Equilibrium in the chemical reaction.
- Equilibrium with the surrounding factors like pressure.
