\(\mathrm{KO}_2\) is used in space and submarines because it
\(\mathrm{KO}_2\) is used in space and submarines because it
Show Hint
KO\(_2\) is used in life-support systems because it regenerates oxygen from carbon dioxide.

- absorb CO\(_2\) and increase O\(_2\) concentration
- absorb moisture
- absorb CO\(_2\)
- produce ozone
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Potassium superoxide reacts with CO\(_2\) to produce O\(_2\).
Step 2: Detailed Explanation:
Reaction: \(4\mathrm{KO}_2 + 2\mathrm{CO}_2 \rightarrow 2\mathrm{K}_2\mathrm{CO}_3 + 3\mathrm{O}_2\).
It absorbs exhaled CO\(_2\) and releases O\(_2\), making it useful in closed environments.
Step 3: Final Answer:
Absorb CO\(_2\) and increase O\(_2\) concentration.
