Question

EASY CHEM Q
Chemical equilibrium is established:


when the reactants stop forming products because there are equal amounts of both

when the products stop forming reactants because there are equal amounts of both

when the reactions cease in both directions because they are now equal

when the rate of formation of products and the rate of formation of reactants becomes steady and equal, but does not stop the reaction


I feel like the answer could be either 3 or 4.
