Question

multiple choice question
reversible reactions usually exist in a state of equilibrium, in which

the ratio of products to reactants is stable
the amount of products and reactants is equal
all reactants have been absorbed by the products

Explanation:

In a state of equilibrium for reversible reactions, the forward and reverse reaction rates are equal, leading to a stable ratio of products to reactants. The amounts of products and reactants are not necessarily equal, and not all reactants are absorbed by products as the reaction is ongoing in both directions.

Answer:

the ratio of products to reactants is stable
