$CaCO _{3}( s ) \rightarrow CaO ( s )+ CO _{2}( g )$ the values of $\Delta H ^{\circ}$ and $\Delta S^{\circ}$ are $+179.1 kJ mol ^{-1}$ and $160.2\,J / K$ respectively at $298 \,K$ and $1 \,bar$. Assuming that $\Delta H ^{\circ}$ and $\Delta S ^{\circ}$ do not change with temperature, temperature above which conversion of lime-stone to lime will be spontaneous is ........... $K$
