Question

Temperature influences chemical reactions. Glow sticks use chemical reactions to produce light. One kind of glow stick produces light for about 4 hours on a summer night. What will happen to this kind of glow stick when one is used on a very cold winter night?

A. It will be dimmer and not last very long.

B. It will be dimmer and last longer.

Answer 1

A. It will be dimmer and not last very long.

Step-by-step explanation:

Hello.

In this case, since warmer temperatures favor the chemical reactions that produce lights, we can infer that lower temperatures such as those during very cold winter nights will not favor the reaction but disfavor them, causing them to undergo slower, less efficiently and lasting for less time, therefore, answer is A. It will be dimmer and not last very long.

This is supported by the theories explaining how fast chemical reactions undergo upon different temperatures conditions, which commonly, at higher temperatures, reaction rates are higher.
