Calcium oxide and carbon dioxide combine to form calcium carbonate in the reversible reaction: CaO + CO2 ⇌ CaCO3 When the reaction is at dynamic equilibrium, which statement must be true? (1 point) Responses The reaction has run out of carbon dioxide or calcium oxide. The reaction has run out of carbon dioxide or calcium oxide. The forward and reverse reactions have stopped. The forward and reverse reactions have stopped. The concentration of calcium carbonate is increasing. The concentration of calcium carbonate is increasing. Calcium carbonate and calcium oxide are formed at the same rate.

Calcium carbonate and calcium oxide are formed at the same rate.
Is this right
Yes, that is correct. At dynamic equilibrium, the forward and reverse reactions are occurring at the same rate, resulting in the formation of calcium carbonate and calcium oxide at equal rates.
