Question

Which of the following reactions is an example of use of water gas in the synthesis of other compounds?

Options

• \[\ce{CH4 (g) + H2O (g) ->[1270 K][Ni] CO (g) + H2 (g)}\]

• \[\ce{CO (g) + H2O (g) ->[673 K][Catalyst] CO2 (g) + H2 (g)}\]

• \[\ce{C_{{n}}H_{2{n} + 2} + {n}H2O (g) ->[1270 K][Ni] {n}CO + (2n + 1) H2}\]

• \[\ce{CO (g) + 2H2 (g) ->[Cobalt][Catalyst] CH3OH (l)}\]

Answer 1

\[\ce{CO (g) + 2H2 (g) ->[Cobalt][Catalyst] CH3OH (l)}\]

Explanation:

Water gas is used in synthesis of compounds like methanol.
