Homework Answers
A reaction in which bonds are broken and made is called chemical reaction.
or
a process that involves rearrangement of the ionic or molecular structure of a substance, as distinct from a change in physical form or a nuclear reaction.

A reaction is said to be ________ if the bonds formed during the reaction are stronger than the bonds broken. A) exergonic B) endergonic C) endothermic D) exothermic E) spontaneous I know the answer is exothermic but I'm confused as to why. Wouldn't having stronger bonds formed than bonds broken mean that delta_H is positive since the enthalpy on the products is bigger than the reactants thus making it endothermic?
