What is K for CaCO₃(s) ⇌ CaO(s) + CO₂(g)?
A.K = [CO₂]
B.K = [CaO][CO₂] / [CaCO₃]
C.K = 1 / [CO₂]
D.K = [CaO] / [CaCO₃]
Explanation
Core Concept
Both solids are omitted, leaving only the gaseous product. Its concentration (or partial pressure) alone defines this equilibrium.
Correct Answer
AK = [CO₂]
