Question

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

• A. $CH_{4(g)} + H_{2}O_{(g)}\underset{Ni}{\overset{\quad 1270\quad}{\rightarrow}}CO_{(g)} + H_{2(g)}$
• B. $CO_{(g)} + H_{2}O_{(g)}\underset{Catalyst}{\overset{\quad 673K\quad}{\rightarrow}}Co_{2(g)} + H_{2(g)}$
• C. $C_{n}H_{2n + 2} + nH_{2}O_{(g)}\underset{Ni}{\overset{\quad 1270\quad}{\rightarrow}}nCO + (2n + 1)H_{2}$
• D. $CO_{(g)} + 2H_{2(g)}\underset{Catalyst}{\overset{\quad Cobalt\quad}{\rightarrow}}CH_{3}OH_{(I)}$

Answer 1

Answer: (D)

$CO_{(g)} + 2H_{2(g)}\underset{Catalyst}{\overset{\quad Cobalt\quad}{\rightarrow}}CH_{3}OH_{(I)}$

Answer 2

: The mixture of CO and $H_{2}$is called water gas. As this mixture of Co and $H_{2}$ is used for the synthesis of methanol and a number of hydrocarbons, it is also called ‘synthesis gas’ or ‘syngas’.
