Question

In a science experiment, a student takes three glow sticks and places them in beakers of water of varying temperatures. Beaker 1 is at 5 degrees Celsius. Beaker 2 is at 25 degrees Celsius, and beaker 3 is at 50 degrees Celsius. Which statement accurately compares and contrasts the reactions that occur in the beakers?

Answer 1

D) All three glow sticks will light up. The glow stick in beaker 3 will shine brighter but will fade faster than the glow stick in beaker 2 because the reaction occurs at a higher rate in warmer temperatures.

Step-by-step explanation:

Answer 2

The chemical reaction in Beaker 3 will be the fastest, while in Beaker 1 it will be the slowest.

Step-by-step explanation:

Chemical reactions take place quicker at higher temperatures because the molecules have higher kinetic energy to make effective collisions between one another. Glow sticks work by converting chemical energy to light energy, the phenyl oxalate ester is a liquid contained in it that is mixed with fluorescent dye. Snapping the glow stick releases the hydrogen peroxide from the glass vial which starts this chemical reaction.

Hope that answers the question, have a great day!
