Which of these is an oxidation half-reaction? upper v superscript 3 plus, plus e superscript minus right arrow upper v superscript 2 plus. upper f lower e, right arrow upper f lower e superscript 3 plus, plus 3 lower e superscript minus. upper c superscript 4 plus, plus 2 e superscript minus right arrow upper c superscript 2 plus.

Respuesta :

Among the given reactions, those reaction which is an oxidation half-reaction is Fe ā†’ FeĀ³āŗ + 3eā».

What is oxidation reaction?

Oxidation reaction in terms of electron will be described as those reactions in which removal of electron takes place.

  • VĀ³āŗ + eā» ā†’ VĀ²āŗ

In this reaction addition of electron takes place, so it is not an oxidation reaction.

  • Fe ā†’ FeĀ³āŗ + 3eā»

In this reaction removal of electrons takes place, so this is an oxidation reaction.

  • Cā“āŗ + 2eā» ā†’ CĀ²āŗ

In this reaction addition of electron takes place, so it is not an oxidation reaction.

Hence Fe ā†’ FeĀ³āŗ + 3eā» shows oxidation half-reaction.
