Bond Energies Tier 3 Vocabulary quiz

Exothermic reaction definition

• A reaction where there was less energy in the bonds of the reactants than there was energy in the bonds of the products so energy is taken in from the surroundings

• A reaction where there was more energy in the bonds of the reactants than there was energy in the bonds of the products so energy is given out to the surroundings

• A reaction where there the same amount of energy in the bonds of the reactants as there was energy in the bonds
