This is not a redox reaction. None of the species are reduced and none are oxidized.
<h3>What is redox reaction?</h3>
A chemical reaction known as an oxidation-reduction (redox) reaction includes the exchange of electrons between two substances. An oxidation-reduction reaction is any chemical process in which a molecule, atom, or ion experiences a change in its oxidation number as a result of gaining or losing an electron.
Redox reactions are those in which one chemical is reduced and another is oxidized. Here, oxygen is being introduced, which causes C to oxidize into CO, and oxygen is being removed, which causes ZnO to decrease to Zn. It is a redox reaction as a result.
Redox reactions are those in which there is a change in the oxidation number, with both an increase and a drop in number.
