Chemistry · JEE Main · NTA Exams — p-Block Elements

\(\mathrm{C}_{(\mathrm{s})}+\mathrm{H}_{2} \mathrm{O}_{(\mathrm{g})} \xrightarrow{473-1273 \mathrm{~K}} \mathrm{CO}_{(\mathrm{g})}+\mathrm{H}_{2(\mathrm{~g})}\)
\(2 \mathrm{C}_{(\mathrm{s})}+\mathrm{O}_{2(\mathrm{~g})}+4 \mathrm{~N}_{2(\mathrm{~g})} \xrightarrow{1273 \mathrm{~K}} 2 \mathrm{CO}_{(\mathrm{g})}+4 \mathrm{~N}_{2(\mathrm{~g})}\)
\(2 \mathrm{C}_{(\mathrm{s})}+\mathrm{O}_{2(\mathrm{~g})} \xrightarrow{\Delta} 2 \mathrm{CO}_{(\mathrm{g})}\)
\(\mathrm{HCOOH} \xrightarrow[\text { conc. } \mathrm{H}_{2} \mathrm{SO}_{4}]{373 \mathrm{~K}} \mathrm{H}_{2} \mathrm{O}+\mathrm{CO}\)

Answer

(D) HCOOH [ conc. H _ 2 SO _ 4 ] 373 ~K H _ 2 O + CO
