Question

Which of the following is the best explanation why some reactions appear to stop before all the reactants are converted to products? (3 points)

The reaction goes to completion.

The reaction reaches equilibrium and the products stop being formed.

The reversible reaction occurs at the same rate.

The limiting reactant prevents the forward reaction occurring.

Answer 1

The reversible reaction occurs at the same rate.

Step-by-step explanation:

When a chemical reaction reach the equilibrium state, the forward reaction ( reactants to products) and the reversible reaction (products to reactants) have the same speed (rate). The concentrations of the products and reactants at the equilibrium state are constant but the reaction never stops.
