Breaking a chemical bond is a process that is:
ASpontaneous
BCatalytic
CEndothermic
DExothermic
Answer & Solution
Correct answer: C. Endothermic
1. Bond energy is stored when atoms are held together.
2. It is essential to remember that energy must be added to break chemical bonds.
3. That makes bond breaking an endothermic process.
4. Forming chemical bonds releases energy, which is exothermic.
