Answer : The most likely happens during this reaction is, Oxidation-reduction
Explanation :
The balanced reaction will be,
In this reaction, neutral iron loses 3 electrons and oxidizes in (+3) state, and neutral oxygen gains 2 electrons and reduces in (-2) state,
When iron react with oxygen gas to give iron oxide. This process is known as iron rusting. During the reaction, oxidation-reduction process occurs.
Oxidation : It is a type of chemical reaction in which a substance loses its electrons. Or we can say that in oxidation, the oxidation number increases.
Reduction : It is a type of chemical reaction in which a substance gains its electrons. Or we can say that in reduction, the oxidation number decreases.
The overall reaction is given by:
The fast step reaction is given as:
The slow step reaction is given as:
(slow step
)
Now, the expression for the rate of reaction of fast reaction is:
The expression for the rate of reaction of slow reaction is:
Slow step is the rate determining step. Thus, the overall rate of formation is the rate of formation of slow reaction as takes place in this reaction.
The expression of rate of formation is:
= (1)
Now, consider that the fast step is always is in equilibrium. Therefore,
Substitute the value of in equation (1), we get:
=
=
Thus, rate law of formation of in terms of reactants is given by
