Step 4: Model the energy change in the reaction. a) Create an energy graph that illustrates the energy change in the reaction.
b) Construct your graph on a blank sheet of paper. Be sure to label the axes, provide a title, and
identify the reactants and products on the graph.

Aglow stick contains a glass vial with chemicals. when the glow stick is bent, the vial breaks and the chemicals react to produce a glow. a science student observes that a glow stick kept in the freezer glows for a longer duration than a glow stick kept at room temperature. what conclusion can be drawn based on the observation? be sure to note the outcome and test variables in the conclusion.
