What is the byproduct of the reaction that occurs in CO2 absorbers?

In the reaction that occurs in CO2 absorbers, the primary processes involve the absorption of carbon dioxide from the environment, typically through a chemical reaction with absorbent materials. During this process, the absorbed carbon dioxide is often converted into other compounds, leading to the production of water as a byproduct. Additionally, the absorption process is exothermic, meaning it releases heat.

Consequently, both water and heat are generated as byproducts of the reaction in CO2 absorbers. This makes D the correct answer, reflecting the dual output of water and heat during the absorption process. Understanding these byproducts is crucial for grasping the operational dynamics of CO2 absorbers, particularly in applications related to environmental control and carbon capture technologies.
