Question

Examine a student's final answer: "ΔH = - 13 kcal." The - 13 kcal means this reaction is _

Answer 1

The reaction is exothermic

Explanation:

An exothermic reaction is a reaction in which heat is liberated or released to the surrounding. In this kind of reaction ( i.e exothermic), the change in enthalpy, ΔH, is negative and less than zero.

Since student got an enthalpy change, ΔH that is negative ( ΔH = - 13 kcal), the reaction is an exothermic reaction.
