For the reaction $CaCO_{3(s)} \to CaO_{(s)} + CO_{2(g)}$,given $\Delta H^o = 178.3 \, kJ$ and $\Delta S^o = 160 \, J \cdot K^{-1}$. At what temperature will the reaction become spontaneous?
Difficult
View SolutionCompare the following criteria for spontaneity of a reaction based on the values of $\Delta_{\text{r}}H^0$,$\Delta_{\text{r}}S^0$,and $\Delta_{\text{r}}G^0$:
$\Delta_{\text{r}}H^0$ $\Delta_{\text{r}}S^0$ $\Delta_{\text{r}}G^0$ Description $(a) (+)$ $(-)$ $(+)$ $(i) \text{ Non-spontaneous at all temperatures}$ $(b) (-)$ $(-)$ $(-)$ $(ii) \text{ Spontaneous at low temperatures}$ $(c) (-)$ $(+)$ $(-)$ $(iii) \text{ Spontaneous at all temperatures}$
| $\Delta_{\text{r}}H^0$ | $\Delta_{\text{r}}S^0$ | $\Delta_{\text{r}}G^0$ | Description |
