Calcium oxide (Lime) is usually produced by heating and decomposing limestone (CaCO3), a cheap and abundant mineral, in a process: CaCO3 (s) CaO (s)+CO2 (g) a) Limestone at 25°C is fed to a continuous calcination reactor. The calcination is complete, and the products leave at 900 °C. Taking 1 metric ton (1000 kg) of limestone as a basis and elemental species [Ca(s), C(s), O2(g)] at 25°C as references for enthalpy calculations, prepare and fill in an inlet-outlet enthalpy table and...

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, 45 g of CaCO3 is heated at 500°C in a 5.0 L vessel. The pressure of CO2 is 0.21 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...
