Question

Which of the following substances is formed when CO reacts with $H_{2}O$ at 773 K in the presence of $F{e}_2{O}_3.C{r}_2{O}_3$ (catalyst)?

• A. Methane
• B. only carbon dioxide
• C. both carbon dioxide and dihydrogen
• D. Carbon monoxide

Answer 1

The correct option is C both carbon dioxide and dihydrogen

water gas shift reaction
$C{O}_{\left(gas\right)}+H_2{O}_{\left(gas\right)}\underset{F{e}_2{O}_3.C{r}_2{O}_3}{\overset{773K}{\to }}C{O}_2+2H_2$
$C{O}_2$ is dissolved in water under high pressure (20-25 atm) and the $H_2$ left undissolved is collected.
