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, 30 g of CaCO3 is heated at 500°C in a 5.0 L vessel. The pressure of CO2 is 0.13 atm after 6.0 minutes. What is the average rate of CO2 production in moles per minute during the 6 minutes? (Enter in mol/min.)   If you assume this rate of decomposition remains constant, how many minutes will it take for the entire sample of CaCO3 to decompose?
