Question

write a letter to editor

Answer 1

Answer:

The equilibrium constant for the reaction CaCO3(s) ⇌ CaO(s) + CO2 (g) is Kc= [CO2]

The equilibrium reaction is

CaCO3(s) ⇌ CaO(s) + CO2 (g)

Molar concentration of pure solids or liquids is constant.

[CaCO3(s)] = [CaO(s)] = 1

∴ Kc = [CO2]

Answer 2

Answer:

The equilibrium constant for the reaction CaCO3(s) CaO(s) + CO2 (g), is. Molar concentration of pure solids or liquids is constant. Therefore [CaCO3(s)] = [ CaO(s)] = 1

The expression for the equilibrium constant will be K=[NO]2[Cl2][NOCl]2.
