Chemistry Question on GROUP 14 ELEMENTS

Which of the following is water-gas shift reaction?

A

\ceC(s)+H2O(g)−>[1270K]CO(g)+H2(g)\ce{ C(s) + H_2 O(g) ->[1270 K] CO(g) + H_2 (g)}

B

\ceCH4+H2O(g)−>[1270K]CO(g)+3H2(g)\ce{ CH_4 + H_2 O(g) ->[1270 K] CO(g) + 3H_2 (g)}

C

\ceCO(g)+H2O(g)−>[1270K][ironchromate]CO2(g)+H2(g)\ce{ CO(g) + H_2 O(g) ->[1270 K][\text{ironchromate}] CO_2(g) + H_2 (g)}

D

\ce2H2O(l)+H2O(g)−>[electrolysis][traces of acid/base]2H2(g)+O2(g)\ce{ 2H_2O(l) + H_2 O(g) ->[\text{electrolysis}][\text{traces of acid/base}] 2H_2 (g) + O_2 (g) }

Answer

\ceCO(g)+H2O(g)−>[1270K][ironchromate]CO2(g)+H2(g)\ce{ CO(g) + H_2 O(g) ->[1270 K][\text{ironchromate}] CO_2(g) + H_2 (g)}

Explanation

Solution

The chemical reaction in which carbon monoxide of the syn gas reacts with steam to give carbon dioxide dihydrogen is called water gas shift reaction. In this reaction, syn gas is oxidised by mixing it with more steam at 673 K673\, K in the presence of iron chromate or ferric oxide and little chromium oxide (\left(\right. at 450∘)\left.450^{\circ}\right) as catalyst.
