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, 40 g of CaCO₃ is heated at 450°C in a 5.0 L vessel. The pressure of CO₂ is 0.12 atm after 7.0 minutes. What is the average rate of CO₂ production in moles per minute during the 7 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?
