Reaction.
If more Energy is absorbed than released, the Reaction is…
Endothermic.
More Energy is required to break Bonds than is released from making new Bonds, making it an ___ process.
Endothermic.
The change in Energy is ___ when the Products have more Energy than the Reactants.
Positive.
A Reaction with a Positive change in Energy is…
Endothermic.
If more Energy is released than is absorbed, then the Reaction is…
Exothermic.
More Energy is released when new Bonds are formed than energy required to break the Bonds in the Reactants, making it an ___ process.
Exothermic.
The change in Energy is ___ when the Products have less Energy than the Reactants.
Negative.
A Reaction with a Negative change in Energy is…
Exothermic.
Each Chemical Bond has a specific ___ associated with it.
Bond Energy.
Define ‘Bond energy’:
Amount of Energy required to break the Bond or the amount of Energy given out when the Bond is formed.
“Total Energy In”=
Total of all Bond Energies of all Reactants.
“Total Energy Out”=
Total of all Bond Energies of all Products.
