Problem

Calculate ΔHrxn for the reaction CaO(s) + CO2(g) → CaCO3(s) given these reactions and their ΔH values: 

Express the enthalpy in kilojoules to one decimal place.

Ca(s) + CO2(g) + 1/2O2 → CaCO(s)   ΔH = −814.1 kJ

2Ca(s) + O2(g) → 2CaO(s)                    ΔH = −1269.8 kJ


Solution

To find the ΔHrxn, we need to use the Hess's Law where we have to rearrange the given equations to get the desired reaction.
