The equation that represents the water-gas shift reaction is :

Multiple Choice Options

A CO(g) + H2O(g) $\mathrel{\mathop{\kern0pt\longrightarrow}\limits_{Catalyst}^{673K}}$ CO2(g) + H2(g)
B CH4(g) + H2O(g) $\mathrel{\mathop{\kern0pt\longrightarrow}\limits_{Ni}^{1270K}}$ CO(g) + 3H2(g)
C C(s) + H2O(g) ⟶1270K CO(g) + H2(g)
D 2C(s) + O2(g) + 4N2(g) ⟶1273K 2CO(g) + 4N2(g)

Step-by-Step Verified Solution

(A) Water gas shift reaction
CO(g) + H₂O(g)

\mathrel{\mathop{\kern0pt\longrightarrow}\limits_{Catalyst}^{673K}}

CO₂(g) + H₂(g)

(B) Water gas is produced by this reaction
CH₄(g) + H₂O(g)

\mathrel{\mathop{\kern0pt\longrightarrow}\limits_{Ni}^{1270K}}

CO(g) + 3H₂(g)

(C) Water gas is produced by this reaction
C(s) + H₂O(g)

\overset{1270 K}{⟶}

CO(g) + H₂(g)

(D) Producer gas is produced by this reaction
2C(s) + O₂(g) + 4N₂(g)

\overset{1273 K}{⟶}

2CO(g) + 4N₂(g)
