The following reaction is used in some self-contained breathing devices as a source ofO2(g). 4KO2(s)+2CO2(g)2K2CO3(s)+3O2(g)Kp=28.

The following reaction is used in some self-contained breathing devices as a source ofO2(g).

4KO2(s)+2CO2(g)⇌2K2CO3(s)+3O2(g)Kp=28.5at25∘C

Suppose that a sample ofCO2(g)is added to an evacuated flask containingKO2(s)and equilibrium is established. The equilibrium partial pressure ofCO2(g)is found to be 7.17×10−2atm.

Part AWhat is the equilibrium partial pressure of O2(g)?Part BWhat is the total gas pressure at the equilibrium?
