Final answer:
A glow stick reaction, which is a chemiluminescent process, does not result in a change of energy measured with temperature. Unlike exothermic and endothermic reactions, which either release or absorb heat, glow sticks convert chemical energy directly into light energy.
Step-by-step explanation:
The student asked which of the following reactions did not result in a change of energy measured with temperature. The options include an exothermic reaction, an endothermic reaction, a glow stick reaction, and a synthesis reaction.
An exothermic reaction is one where energy is released, usually in the form of heat, causing the temperature to rise. An endothermic reaction is one that absorbs energy from the surroundings, typically resulting in a temperature drop. A glow stick reaction is a chemiluminescent process where chemical energy is converted directly into light energy without a significant change in temperature, making it the correct answer. A synthesis reaction involves the combination of elements or simpler compounds to form a more complex compound and generally involves changes in energy and temperature as well.
