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 answer
At dynamic equilibrium, the rate of the forward reaction (CaO + CO2 → CaCO3) is equal to the rate of the reverse reaction (CaCO3 → CaO + CO2). Therefore, the concentration of each compound must remain constant over time.
