From the calculation as shpwn in the procedure below, the equilibrium constant of the substance is 6.9 * 10^-15.

<h3>What is equilibrium constant?</h3>

The equilibrium constant for the solubility of aa solid in solution is called the solubility product Ksp. The Ksp shows the extent to which a solid is dissolved in solution.

Given that;

Fe(OH)2 ⇄Fe^2+ + 2(OH)^-

Ksp = s(2s)^2

We have s as 1.2 x 10^-5 M

Ksp = 4s^3

Ksp = 4( 1.2 x 10^-5 )^3

Ksp = 6.9 * 10^-15

Yes, it is a correct approach because endothermic reactions absorb heat. In consequence, the amount of heat can be used to classify this reaction.

<h3>Endothermic and exothermic reactions</h3>

An exothermic reaction is a type of chemical reaction that releases heat, thereby increasing the temperature of its surrounding environment.

Conversely, an endothermic reaction can absorb heat, thereby cooling its surrounding environment.

In consequence, the amount of heat measured after the reaction can be indicative of the type of chemical reaction.
