Read the passage and answer the next two questions. Scientists created energy diagrams to correspond to various chemical reactions. These
energy diagrams represented the energy changes of various reactants and products as
the reactions take place. These diagrams showed that endothermic reactions absorb
energy from their surroundings while exothermic reactions released energy into their
surroundings. The diagrams also showed the activation energies associated with
various reactions.
