Answer:
Option B. Keq = [CO2] [CaO]/ [CaCO3]
Explanation:
The balanced equation for the reaction is given below:
CaCO3(s) —> CaO(s) + CO2(g)
The expression for the equilibrium constant, Keq is simply the ratio of the concentration of the products to that of the reactants.
The expression for the equilibrium constant, Keq is given below:
Keq = [CO2] [CaO] / [CaCO3]
