Question

What is the Kc for the following reaction at equilibrium at 800∘C if [CO2]= 0.030 M ? CaCO3(s)⇌CaO(s)+CO2(g)

Answer 1

Answer:

0.030

Explanation:

Step 1: Write the balanced reaction at equilibrium

CaCO₃(s) ⇌ CaO(s) + CO₂(g)

Step 2: Calculate the concentration equilibrium constant

The concentration equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients. It doesn't include solids or pure liquids.

Kc = [CO₂] = 0.030
