Problem 96P

PROBLEM 96P

An emergency breathing apparatus placed in mines or caves works via the chemical reaction:

4 KO2(s) + 2 CO2(g) β†’ 2 K2CO3(s) + 3 O2(g)

If the oxygen supply becomes limited or if the air becomes poisoned, a worker can use the apparatus to breathe while exiting the mine. Notice that the reaction produces O2, which can be breathed, and absorbs CO2, a product of respiration. What minimum amount of KO2 is required for the apparatus to produce enough oxygen to allow the user 15 minutes to exit the mine in an emergency? Assume that an adult consumes approximately 4.4 g of oxygen in 15 minutes of normal breathing.

Step-by-Step Solution:
Step 1 of 3

Solution 96P

4 KO2(s) + 2 CO2(g)β†’2 K2CO3(s) + 3 O2(g)
