$CaCO_3( s) \rightarrow CaO(s) + CO_2(g)$
the values of $\Delta H^o$ and $\Delta S^o$ are $+ 179.1\, kJ\, mol^{-1}$ and $160.2\, J/K$ respectively at $298\, K$ and $1\,bar.$ Assuming that $\Delta H^o$ and $\Delta S^o$ do not change with temperature, temperature above which conversion of lime stone to lime will be spontaneous is ............. $\mathrm{K}$
$\begin{gathered}
{\left[ {Al{{\left( {{H_2}O} \right)}_6}} \right]^{ + 3}} + HCO_3^ - \rightleftarrows {\left[ {Al{{\left( {{H_2}O} \right)}_5}OH} \right]^{ + 2}} + {H_2}C{O_3} \hfill \\
