Explanation:
As the given reaction is as follows.
So, according to the balanced equation, it can be seen that rate of formation of will be twice the rate of disappearance of
.
And, it is known that rate of disappearance of reactant will be negative and rate of formation of products will be positive value.
This means that,
Rate of the reaction = -Rate of disappearance of
=
=
= M/s
Therefore, calculate the rate of formation of as follows.
Rate of formation of =
= M/s
Thus, we can conclude that the rate of formation of is M/s.
