Consider the thermal decomposition of CaCO3: The
Chapter 18, Problem 73AP(choose chapter or problem)
Consider the thermal decomposition of \(\mathrm{CaCO}_3\) :
\(\mathrm{CaCO}_3(s) \rightleftarrows \mathrm{CaO}(s)+\mathrm{CO}_2(g)\)
The equilibrium vapor pressures of \(\mathrm{CO}_2\) are \(22.6 \mathrm{mmHg}\) at \(700^{\circ} \mathrm{C}\) and \(1829 \mathrm{mmHg}\) at \(950^{\circ} \mathrm{C}\). Calculate the standard enthalpy of the reaction. [Hint: See Problem 18.66(a).]
