Isaac pours water into one container and liquid acetone into another.
He seals both containers. He measures the
gas pressure above both liquids. At the same
temperature, the pressure of the acetone gas
is higher than the pressure of water vapor.
Which liquid requires more thermal energy to
change from a liquid to a gas? Explain

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.
