Carbon monoxide, CO, and oxygen, O2, react according to
2CO(g) + O2(g) †’ 2CO2(g)
Assuming that the reaction takes place and goes to completion, determine what substances remain and what their partial pressures are after the valve is opened in the apparatus represented in the accompanying figure. Also assume that the temperature is fixed at 300 K.
