Which of the following reaction increases, production of dihydrogen from synthesis gas ?

Options

A. `CH_4(g)+H_2O(g)overset(1270K)underset("Ni")rarrCO(g)+3H_2(g)`
B. `C(s)+H_2O(g)overset(1270K)rarrCO(g)+H_2(g)`
C. `CO(g)+H_2O(g)overset(673K)underset("Catalyst")rarrCO_2(g)+H_2(g)`
D. `C_2H_6+2H_2O(g)overset(1270K)underset("Ni")rarr2CO+5H_2`

Answer

C

Explanation

The process of producing syn gas or synthesis gas from coal is called ‘coal gasification
`underset("Coal")(C(s))+underset("Steam")(H_2O(g))overset(1270K)underset("Ni")rarrunderset("Syn gas")(underbrace(CO(g)+H_2(g)))`
The production of hydrogen can be increased by reacting carbon monoxide of the syn gas with steam in the presence of iron chromate as a catalyst at 673 K.
`CO(g)+H_2O(g)overset("FeCrO_(4),673K)rarrCO_2(g)+H_2(g)`
`CO_2` is removed by scrubbing with a solution of sodium arsenite.
