Question
Endothermic and Exothermic Reactions
Instructions
By referencing (use APA
citations) from the internet, textbook, or research article, post one chemical
reaction that is considered an exothermic reaction and another one that is
considered as an endothermic reaction.
In your post, please address
the following topics:
• State why you chose these 2
reactions (1 exothermic and 1 endothermic).
.Add the applications of the 2
reactions you chose.
Requirements
• Complete your initial post
by the due date.
• Read the posts from 2 of
your fellow students and add more information to the application of the
reaction.
Feel free to post a gif or a
vimeo video or a link to a YouTube video and feel free to include a podcast
link if you wish to explain the importance of the molecule
Expert Solution
Exothermic Reaction: Methane
combustion
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g) + Heat
Endothermic
Reaction: Photosynthesis
6CO2(g) + 6H2O(l) + light energy → C6H12O6(aq) + 6O2(g)
I chose
Methane combustion since it is a classic illustration of an exothermic process.
It commonly generates energy and releases it as heat for heating, cooking, and
energy generation. The reaction shows the energy conservation law because the
energy produced during it is transferred to the environment as heat. The
essential endothermic reaction of photosynthesis keeps life on Earth going. It
exemplifies how light energy influences chemical reactions. It also shows how
energy may change from one form, like light, to another, like the molecular
energy in glucose. The process must be endothermic to synthesize complex
organic compounds from simpler inorganic materials.
