roducts
OC. The concentrations of reactants and products are not constant.
D. The concentration of the products is higher than that of the reactants.

Answer 1

The products can form reactants, and the reactants can form products

Step-by-step explanation:

Answer 2

B. The products can form reactants, and the reactants can form products.

Step-by-step explanation:

Depending on whether products of a chemical reaction can form their reactants or not, a chemical reaction can be irreversible or reversible.

Irreversible chemical reactions occur in only one direction. The reactants can form products, but the products cannot change back to the reactants.

Reversible chemical reactions occur in both directions, which means that the products can change back to the reactants under certain conditions, as well. This is something that always applies to reversible chemical reactions, which is why option B is the correct one.
