Q8 / 90 · JEE Main 2023 (15 Apr Shift 1) · Chemistry

During water-gas shift reaction

  • Correct answer
    A
    Carbon monoxide is oxidized to carbon dioxide.
  • B
    Water is evaporated in presence of catalyst.
  • C
    Carbon is oxidized to carbon monoxide.
  • D
    Carbon dioxide is reduced to carbon monoxide.

Solution

The reaction between CO of syn gas and steam in presence of catalyst is called water gas shift reaction.

CO+H2O→CO2+H2O

This reaction increases the yield of hydrogen obtained from coal gasification reaction as shown below.

C+H2O⟶CO+H2⏟syn gas

Hence, the correct answer is option: 'A'.
