Some ionic solids become less soluble in water as the temperature is raised. If you compare the solubility of a gas in water at two different temperatures, you find the gas is more soluble at the lower temperature. The solubility of most ionic solids in water decreases as the temperature of the solution increases. The solubility of most gases in water decreases as the temperature increases because water is breaking its hydrogen bonding to the gas molecules as the temperature is raised.

i'm assuming that the correct answer is indeed the first one/ "a"..

58750.08068 is the answer i think

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
