• A. $CO ( g )+ H _{2} O ( g ) \xrightarrow[{\text{Catalyst}}]{673 \,k} CO _{2}( g )+ H _{2}( g )$
• B. $CH_{4} (g) +H_{2}O (g) \xrightarrow[{Ni}]{1270\,K} CO(g)+3\,H_{2}(g)$
• C. $C(s) +H_{2}O(g) \xrightarrow{1270 K } CO ( g )+ H _{2}( g )$
• D. $2 C ( s )+ O _{2}( g )+4 N _{2}( g ) \xrightarrow{1273 K } 2 CO ( g )+4 N _{2}( g )$

Answer 1

Answer: (A)

(1) Water gas shift reaction
$CO _{( g )}+ H _{2} O _{( g )} \xrightarrow[{\text{catalyst }}]{673\,K} CO_{2(g)}+H_{2(g)}$
(2) Water gas is produced by this reaction
$ CH _{4( g )}+ H _{2} O _{( g )} \xrightarrow[{Ni}]{1270\,K} B CO _{( g )}+3 H _{2( g )}$
(3) Water gas is produced by this reaction
$C _{( s )}+ H _{2} O _{( g )} \xrightarrow{1270 K } CO _{( g )}+ H _{2( g )}$
(4) producer gas is produced by this reaction.
$2 C _{( s )}+ O _{2( g )}+4 N _{2( g )} \xrightarrow{1270 K } 2 CO _{( g )}+4 N _{2( g }$
