Question

What is the spontaneous redox reaction?

Answer 1

1. Redox reactions are reactions in which loss or gain of electrons occurs between an atom.
2. Loss of electrons is so-called Oxidation, whereas gain of electrons is so-called Reduction.
3. The simultaneous process of loss or gain in electrons is termed a Redox reaction.
4. Spontaneous reactions are reactions in which no external force is applied to proceed with the reaction.
5. If the standard electrode potential of the redox reaction is positive then the reaction will proceed in the forward direction and be spontaneous in nature.
6. Such type of reactions are used in producing electricity for example galvanic cells.
7. The spontaneous redox reaction can be mathematically presented as:${\mathrm{E}}_{\mathrm{redox}\mathrm{reaction}}^0={\mathrm{E}}_{{\mathrm{oxidation}\mathrm{reaction}}_{}}^0+{\mathrm{E}}_{\mathrm{reduction}\mathrm{reaction}}^0$
8. For spontaneous reaction${\mathrm{E}}_{\mathrm{redox}\mathrm{reaction}}^0>0$
