The thermal decomposition of limestone takes place as

\[ \mathrm{CaCO}_{3}(\mathrm{~s}) \rightleftharpoons \mathrm{CaO}(\mathrm{s})+\mathrm{CO}_{2}(\mathrm{~g}) \]

Calculate the decomposition pressure at \(1000 \mathrm{~K}\) when standard enthalpy, \(\Delta H_{1000}^{0}\), and entropy, \(\Delta S_{1000}^{0}\), change of the reaction are \(1.7553 \times 10^{5} \mathrm{~J}\) and \(150.3 \mathrm{~J} / \mathrm{mol}-\mathrm{K}\).
