Question

At which of the following temperatures is the chance of molecules aligning just right for a chemical change the highest?

50 °F
40 °F
30 °F
20 °F

Answer 1

50 °F would give a possible chance of the molecules aligning just right for a chemical change because the higher the temperature, the more excited, or active the molecules will become. When there is more activity, there is more collision, which results in heat from the friction, and they will have a higher chance for chemical change because of the frequent run-ins of these molecules.

Hope this helps! If it's right or wrong, please let me know :)

Answer 2

50 degrees F, because this is the highest temperature, and thus the molecules will be the most active. With more activity they will have more collisions, with more collisions they have higher chances of combining for a chemical change.
