Vedclass · Answer

(A) The industrial production of hydrogen from water gas (also known as the Bosch process) involves the 'water-gas shift reaction'.$1$. The mixture of $CO$ and $H_2$ is mixed with excess steam and passed over an iron chromate catalyst at $673 \ K$.$2$. The reaction is: $CO(g) + H_2O(g) \xrightarrow{FeCrO_4} CO_2(g) + H_2(g)$.$3$. The resulting $CO_2$ is then removed by scrubbing the mixture with a solution of sodium arsenite or potassium hydroxide (alkali),leaving behind pure $H_2$.

Which of the following statements is true regarding the industrial production of hydrogen gas from water gas $(CO + H_2)$?
