Which of the following reactions is an example of a redox reaction?
Redox reaction
Electrons travel between reactants that are already in touch in a redox reaction. Changes in the oxidation states of the organisms can then be used to measure how so many atoms are transferred.
The explanation for the correct option:
Option (C):
Where Xenon (Xe) is oxidized and Oxygen (O2) is reduced. The oxidation number of Xe grows from +4 to +6 in the chemical equation above, while the oxidation number of oxygen reduces from +1 to 0. Therefore, it is an example of a redox reaction.
The explanation for the incorrect options:
Option (A): . In this reaction, there is no change in the oxidation state of Xe, hence this doesn't count for redox reaction. has +6 oxidation state in on the reactant side and on the product side.
Option (B): . In this reaction, there is no change in the oxidation state of Xe, hence this doesn't count for redox reaction. has +6 oxidation state in on the reactant side and on the product side.
Option (D): . In this reaction, there is no change in the oxidation state of Xe, hence this doesn't count for redox reaction. has +2 oxidation state in on the reactant side and on the product side.
Hence, these options are incorrect.
Therefore, option (C) is the correct answer.
