Answer:
At equilibrium, the rate of production of reactants is the same as the rate of production of products.
Step-by-step explanation:
Chemical equilibrium is the state of a system where no changes are observed in the concentration of reagents or products, over time, that is, they remain constant.
The chemical equilibrium happens in reversible reactions, that is, reactions that can occur in both directions; that is, not only can reagents be converted into products, but the latter can be decomposed into the original substances.
In the chemical equilibrium, both speeds, that of the direct reaction and that of the reverse reaction, are equal. The products are formed at the same speed as they are consumed, so they do not experience variation in their concentration. If the external conditions of the system ( as pressure and temperature) remain unchanged, the concentrations of reagents and products will remain constant.
So, at equilibrium, the rate of production of reactants is the same as the rate of production of products.
