3. The graphs below show the amount of energy present during two chemical reactions. One of the reactions is an energy-absorbing reaction, the other is an energy-releasing reaction. Label the type of reaction for each, label the energy level for the reactants and products, then draw an arrow on each to show the energy of activation.



4. What is released or absorbed whenever chemical bonds form or are broken?
                                                                                                                                           
5. What is the energy of activation?
                                                                                                                                           
6. Of the two reactions shown, which one is more likely to start spontaneously and why?
