<p align="justify">Una de las reacciones más importantes de la industria química es la descomposición del carbonato de calcio (sólido) en dióxido de carbono (gas) y óxido de calcio (sólido). Si el ΔS<sup>0</sup> de la reacción es 159 J/K y las entalpías estándar de formación del carbonato de calcio, dióxido de carbono y óxido de calcio son: ΔH<sup>0</sup><sub>f</sub> CaCO<sub>3</sub> (s) = -1207 KJ/mol; ΔH<sup>0</sup><sub>f</sub> CaO (s) = -633 KJ/mol; Δ H<sup>0</sup><sub>f</sub> CO<sub>2</sub> (g) = -393 KJ/mol. <span style="font-size: 10pt; line-height: 1.5em;">Suponiendo que ΔH</span><sup style="line-height: 1.5em;">0</sup><span style="font-size: 10pt; line-height: 1.5em;"> e ΔS</span><sup style="line-height: 1.5em;">0</sup><span style="font-size: 10pt; line-height: 1.5em;"> son constantes. Calcula la temperatura centígrada a partir de la cual la reacción será espontánea. </span></p>
