Bond Energy Calculations Flashcards
All 3 cards in this deck
What is the equation for the overall energy change of a reaction from bond energies?
Energy change = (sum of bond energies broken) − (sum of bond energies made).
In a bond energy calculation, what does a negative energy change tell you about the reaction?
The reaction is exothermic (energy is given out overall).
What unit is used for bond energies and for an energy change calculated from them?
kJ mol (kilojoules per mole).
