Question

Upper C a upper C upper O subscript 3 (s) double-headed arrow upper C a upper O (s) plus upper C upper O subscript 2 (g).

What is the equilibrium constant expression for the given reaction?

Answer 1

b on edge

Step-by-step explanation:

Answer 2

K = [CaO] [CO2] /[CaCO3]

Step-by-step explanation:

Step 1:

The equation for the reaction. This is given below:

CaCO3(s) <==> CaO(s) + CO2(g)

Step 2:

Obtaining an expression for the equilibrium constant.

The equilibrium constant K for a reaction is the ratio of the concentration of the products raised to their coefficient to that of the concentration of the reactant raised to their coefficient.

Since the coefficient in the reaction above is 1, 1, 1, the expression for the equilibrium constant be written as.

K = [CaO] [CO2] /[CaCO3]
