Bond Energies Flashcards
1
Q
What is ‘bond energies’
A
The amount of energy required to break one type of a particular covalent bond
2
Q
What type of process is breaking bonds itself ?
A
An endothermic process
3
Q
What type of reaction is bond formation ?
A
Exothermic
4
Q
How do you determine if an overall reaction is endothermic or exothermic ?
A
You have to compare the total energy required to the total energy released
- Energy required to break bonds minus the energy released by forming bonds
- If the number is negative it is exothermic but if it’s positive it is endothermic
5
Q
If the number overall is negative the reaction is what ?
A
Exothermic
6
Q
If the number overall is positive the reaction is what ?
A
Endothermic
