Hey there!

I attached a screenshot of my chemistry notes from this year on equilibrium constants in particular. Feel free to reference this in the future if you wish.

Based on the information in my attachment, you could construct your constant like this:

$K_{eq} = \frac{[CaO][CO_{2}]}{[CaCO_{3}]}$

I don't think it matters which order your reactants or products are in as long as you have them on the top and bottom where they need to be, so your answer will be B.

Hope this helped you out! :-)

Answer:

Most solids in solution exhibit a general trend of increasing solubility with increasing temperature.

A seed crystal may be added to a supersaturated solution to precipitate excess solute.

Explanation:

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions(Lumen Learning).

When a seed crystal is added to a supersaturated solution, excess solute begin to precipitate because the seed crystal now furnishes the required nucleation site where the excess dissolved crystals now begin to grow.
