Which of the following is water-gas shift reaction?
Options
- AC ( s ) + H 2 O ( g ) ⟶ 1270   K CO ( g ) + H 2 ( g )
- BCH 4 ( g ) + H 2 O ( g ) ⟶ 1270   K CO ( g ) + 3 H 2 ( g )
- CCO ( g ) + H 2 O ( g )   → ironchromate 673 K CO 2 ( g ) + H 2 ( g )
- D2 H 2 O ( l ) → traces   of   acid   / base electrolysis 2 H 2 ( g ) + O 2 ( g )
Correct answer
C. CO ( g ) + H 2 O ( g )   → ironchromate 673 K CO 2 ( g ) + H 2 ( g )
Step-by-step solution
The mixture of CO and H 2 is called as water gas. As the mixture of CO and H 2 is used for the synthesis of methanol and a number of hydrocarbons, it is also called 'syn gas' or synthesis gas. The process of producing 'syn gas' from coal is called coal gasification. C s   +   H 2 O g   →   CO g   +   H 2 g The production of dihydrogen can be increased by reacting carbon monoxide with steam in the presence of iron chromate as a catalyst. CO g   +   H 2 O
