The following reaction is used in some self-contained breathing devices as a source of O2.
4KO2(s) + 2C02(g)---> 2K2CO3(s) + 3O2(g)
Suppose that a sample of CO2(g) is added to an evacuated flask containing KO2(s) and equilibrium is established. The equilibrium partial pressure of CO2(g)is found to be 7.20×10−2atm.
What is the equilibrium partial pressure of O2?
What is the total gas pressure at the equilibrium?
