Question

Why would changing the temperature of a light stick affect the intensity of the

light that it emits? Consider what is occurring at the molecular scale that would affect the
rate of the reaction. Which of these light sticks do you think would stop glowing first?

Answer 1

Increasing temperature typically increases the rate of the chemical reaction. Increasing temperature speeds up the motion of molecules, so they are more likely to bump into each other and react. In the case of glow sticks, this means a hotter temperature will make the glow stick glow more brightly.
