In case of calcination of limestone, CaCO3 CaO + CO2, the addition of more of CaO will result in _______________ in the concentration of CO2?
Correct answer: A. No change
- A. No change
- B. Increase
- C. Decrease
- D. Unpredictable from the data
Explanation
For CaCO₃(s) ⇌ CaO(s) + CO₂(g), the pure-solid activities remain essentially unity. Adding more CaO therefore does not change the equilibrium CO₂ partial pressure or concentration, provided both solid phases are present.
