Problem: A particular kind of emergency breathing apparatus-often placed in mines, caves, or other places where oxygen might become depleted or where the air might become poisoned-works via the following chemical reaction:4KO2(s) + 2CO2(g) → 2K2CO3(s) + 3O2(g)Notice that the reaction produces O2, which can be breathed, and absorbs CO2, a product of respiration. Suppose you work for a company interested in producing a self-rescue breathing apparatus (based on the above reaction) which would allow the user to survive for 13 minutes in an emergency situation.What are the important chemical considerations in designing such a unit?
