उत्तर
Caron monoxide
In the laboratory, CO is prepared by the dehydration of formic acid with conc. H2SO4, at 373 K. The reaction involved is as follows:
\[\ce{HCOOH ->[373 K][conc. H2SO4] H2O + CO\uparrow}\]
CO is commercially prepared by passing steam over hot coke. The reaction involved is as follows:
\[\ce{C_{(s)} + H2O_{(g)} ->[473 - 1273 K] \underset{water gas}{CO_{(g) + H_{2(g)}}}}\]
