STATEMENT-$2$: All chiral molecules have chiral centres.
$2 A ( g ) \rightleftharpoons A _{2}( g )$
at $400\, K$ has $\Delta G ^{\circ}=+25.2\, kJ mol ^{-1}$.
The equilibrium constant $K _{ C }$ for this reaction is $...... \times 10^{-2}$. (Round off to the Nearest integ $\left[\right.$ Use $: R=8.3\, J mol ^{-1} K ^{-1}, \ln 10=2.3$
$\left.\log _{10} 2=0.30,1\, atm =1\, bar \right]$
$[$ antilog $(-0.3)=0.501]$
$CaCO_3( s) \rightarrow CaO(s) + CO_2(g)$
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 ............. $\mathrm{K}$
