Chemical equilibrium is attained when
- reactants in the system are used up
- concentrations of the products are greater than those of the reactants
-
concentrations of the reactants and products remain constant
- reactants stop forming the products
The correct answer is: C
Explanation
Chemical equilibrium is attained whenever the concentration of reactants on the Left hand side and the concentration of the products on the left hand side remain unchanged or constant. Which means the effect of the changes brought on the system in equilibrium has been cancelled according to Le Chatelier's principle. The correct answer is option C
