Answer:
, the reaction is spontaneous.
Explanation:
Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
For the given chemical reaction:
The half cell reactions for the above reaction follows:
Oxidation half reaction:
Reduction half reaction:
To balance the oxidation half reaction must be multiplied by 2 and thus, the balanced equation is:-
Here undergoes oxidation by loss of electrons, thus act as anode. undergoes reduction by gain of electrons and thus act as cathode.
Where both are standard reduction potentials.
<u>Since, , the reaction is spontaneous.</u>
