Question

Question 5 of 30What is the best definition of the enthalpy of reaction, AH?A. The change in the disorder of a system during a reactionB. The energy absorbed or released by a system during a reactionC. The change in the disorder of a system when a solid meltsD. The energy needed to change a solid into a liquidSUBMIT

Answer 1

Answer:

B. The energy absorbed or released by a system during a reaction.

Explanation:

The enthalpy of reaction (ΔH), is the energy absorbed or released by a system during a reaction, and it allows us to know if the reaction is endothermic (absorbs energy) or if it is exothermic (releases energy).
