Which is not a method of preparing carbon monoxide on a commercial scale?

A

C(s)+H2O(g)→473−1273CO(g)+H2(g)C_{(s)} + H_{2}O_{(g)}\overset{\quad 473 - 1273\quad}{\rightarrow}CO_{(g)} + {H_{2}}_{(g)}

B

2C(s)+O2(g)+4N2(g)→1273K2CO(g)+4N2(g)2C_{(s)} + O_{2(g)} + 4N_{2(g)}\overset{\quad 1273K\quad}{\rightarrow}2CO_{(g)} + 4N_{2(g)}

C

2C(s)+O2(g)→Δ2CO(g)2C_{(s)} + O_{2(g)}\overset{\quad\Delta\quad}{\rightarrow}2CO_{(g)}

D

HCOOH→373Kconc.H2SO4H2O+COHCOOH\underset{conc.H_{2}SO_{4}}{\overset{\quad 373K\quad}{\rightarrow}}H_{2}O + CO

Answer

HCOOH→373Kconc.H2SO4H2O+COHCOOH\underset{conc.H_{2}SO_{4}}{\overset{\quad 373K\quad}{\rightarrow}}H_{2}O + CO

Explanation

Solution

: HCCOH on dehydration gives CO. This method is used for producing CO at a small scale.
