The question is incomplete, here is the complete question:
The rate of certain reaction is given by the following rate law:
At a certain concentration of
As we are given that:
Initial rate = 0.120 M/s
Expression for rate law for first observation:
....(1)
Expression for rate law for second observation:
....(2)
Dividing 2 by 1, we get:
Therefore, the initial rate of the reaction will be, 0.03 M/s
