Use standard enthalpies of formation to calculate ΔHrxn∘ for the following reaction. CaO(s)+CO2(g)→CaCO3(s) Enthalpy of ReactionEnthalpy of reaction is defined as the amount of energy released or required to convert one mole of a react...
Rate equation theory for CaO carbonation reaction was developed to replace the assumption of critical product layer thickness with a complete calculation of the rates of CaCO3 nucleation and growth. The model includes rate expressions for the island size distribution function with time evolution, and ...
