A
Released
2
Q
When bonds/intermolecular forces are broken energy is…
A
Required (absorbed).
3
Q
Define Exothermic
A
Energy released making products > energy required to break the reactants. The extra energy created is released to the surroundings.
4
Q
Define Endothermic
A
Energy required to break reactants > energy released in making the products. The extra energy needed is absorbed from the surroundings.
