Answer:
B. CO + H₂O → H₂ + CO₂
Explanation:
Redox reaction -
It is the type of reaction , where the process of oxidation and reduction takes place simultaneously , is known as a redox reaction .
Oxidation refers to the addition of oxygen atom or the removal of hydrogen atom .
And ,
Reduction refers to the addition of hydrogen atom or the removal of the oxygen atom .
From the options given in the question , the only reaction , which have both the process of oxidation as well as reduction , is -
CO + H₂O → H₂ + CO₂
In the above reaction ,
Oxidation process - CO → CO₂ ,
The addition of oxygen atom .
Reduction process - H₂O → H₂ ,
The removal of oxygen atom .
