Question
Give one method for industrial preparation and one for laboratory preparation of CO.

Solution
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:
\[\ce{C_{(s)} + H2O_{(g)} ->[473 - 1273 K] \underset{water gas}{CO_{(g) + H_{2(g)}}}}\]
