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, 70 g of CaCO3 is heated at 600°C in a 5.0 L vessel. The pressure of CO2 is 0.20 atm after 3.0 minutes. What is the average rate of CO2 production in moles per minute during the 3 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?

Question

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, 70 g of CaCO₃ is heated at 600°C in a 5.0 L vessel. The pressure of CO₂ is 0.20 atm after 3.0 minutes. What is the average rate of CO₂ production in moles per minute during the 3 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?
