the oxidation of copper in air has the equilibrium constant of Kp=1.4*10^22 at 25 degrees Celsius, followed by the equation Cu (s) + 1/2 O2 (g) -> CuO (s). If a copper penny was to be put in a sealed and fully evacuated glass vessel and the reaction above reached equilibrium at 25 degreed Celsius, what would be the pressure of oxygen in the vessel in atm? (*assume: 1 atm=1bar)
