Question

Which of the following reactions is an example of use of water gas in the synthesis of other compounds?
(a) $CH_4(g) + H_2O(g) \xrightarrow[Ni]{1270 K} CO(g) + H_2(g)$
(b) $CO(s) + H_2O(g) \xrightarrow[Catalyst]{673K} CO_2(g) + H_2(g)$
(c) $C_nH_{2n + 2} + nH_2O(g) \xrightarrow[Ni]{1270 K} nCO + (2n+1) H_2$
(d) $CO(s) + 2H_2(g) \xrightarrow[Catalyst]{Cobalt} CH_3OH(l)$

Answer 1

(b) and (d)

(b) this is water shift gas reaction, used in making hydrogen gas.

(d) by this method methanol is prepared industrially.
