Calculate the heat produced (in kJ) when 224 gm of CaO is completely converted to $CaC{O}_3$ by

reaction with ${\text{CO}}_{\text{2}}$ at 27°C in a container of fixed volume.  

Given : ${\text{ΔH}}_{\text{f}}^{\text{°}}\left({\text{CaCO}}_{\text{3}}\text{,s}\right)\text{\hspace{0.17em}=\hspace{0.17em}}-\text{\hspace{0.17em}1207kJ/mol}$

${\text{ΔH}}_{\text{f}}^{\text{°}}\left(\text{CaO,s}\right)\text{\hspace{0.17em}=\hspace{0.17em}}-\text{\hspace{0.17em}635kJ/mol}$

${\text{ΔH}}_{\text{f}}^{\text{°}}\left({\text{CO}}_{\text{2}}\text{,g}\right)\text{\hspace{0.17em}=\hspace{0.17em}}-\text{\hspace{0.17em}394kJ/mol\hspace{0.17em}}\left[{\text{Use\hspace{0.17em}R\hspace{0.17em}=\hspace{0.17em}8.3\hspace{0.17em}K}}^{\text{-1}}{\text{mol}}^{\text{-1}}\right]$
