Calcium oxide (CaO), an important ingredient in cement, is produced by decomposing calcium carbonate (CaCO3) at high temperature: CaCO3(s) → CaO(s) + CO2(g) In one particular reaction, 20 g of CaCO3 is heated at 700°C in a 5.0 L vessel. The pressure of CO2 is 0.13 atm after 9.0 minutes. What is the average rate of CO2 production in moles per minute during the 9 minutes? (Enter in mol/min.)
