In conversion of limestone to lime, \[pOH\] the values of\[2A+B\xrightarrow[{}]{{}}products\]and\[L\,mo{{l}^{-1}}{{s}^{-1}}\]are\[mol\,{{L}^{-1}}{{s}^{-1}}\]\[{{s}^{-1}}\]and\[Co=27,Ni=28,Fe=26,Pt=78\]respectively at 298 K and 1 bar. Assuming that\[{{[COC{{l}_{4}}]}^{2-}}\]and\[{{[FeC{{l}_{4}}]}^{2-}}\]do not change with temperature, temperature above which conversion of limestone to lime will be spontaneous is       AIEEE  Solved  Paper-2007
