Answer: Following reactions can also occur :-
[tex]CO(g) + 3H_{2}(g) \rightarrow CH_{4}(g) + H_{2}O(g)[/tex] (Forward reaction)
[tex]CH_{4}(g) + H_{2}O(g) \rightarrow CO(g) + 3H_{2}(g)[/tex] (Backward reaction)
Explanation:
As the given reaction is as follows.
[tex]CO(g) + H_{2}O(l) \rightarrow CO_{2}(g) + H_{2}(g)[/tex]
This is a forward reaction which can also be written as follows.
[tex]CO_{2}(g) + H_{2}(g) \rightarrow CO(g) + H_{2}O(l)[/tex] (Backward reaction)
This carbon monoxide when chemically reacts with newly formed hydrogen gas then it will lead to the formation of methane and water as follows.
[tex]CO(g) + 3H_{2}(g) \rightleftharpoons CH_{4}(g) + H_{2}O(g)[/tex] (equilibrium)
Hence, these reactions can be written as follows.
[tex]CO(g) + 3H_{2}(g) \rightarrow CH_{4}(g) + H_{2}O(g)[/tex] (Forward reaction)
[tex]CH_{4}(g) + H_{2}O(g) \rightarrow CO(g) + 3H_{2}(g)[/tex] (Backward reaction)
