Bond Energy Calculation

Question 1

Is bond forming exothermic or endothermic?

Answer 1

Exothermic because energy is released when new bonds are formed

Question 2

What is the equation for the energy of a reaction?

Answer 2

energy of a reaction/ = energy needed to +- energy released
energy change break bonds in the bonds are formed in
reactants the products

energy = breaking - making

Question 3

Is bond breaking exothermic or endothermic?

Answer 3

Endothermic because energy must be put in to break the bonds
