What is the equilibrium constant expression for the given reaction?

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

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]

answer; protein;

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
