The balanced chemical reaction will be given by
Answer:
Explanation:
Hello,
In this case, since the rate equation turns out as shown below due to the first-order kinetics:
Its integration results:
However, the rate constant is computed by considering the given half-life time as follows:
In such a way, the required time in minutes to diminish the concentration by 66.8% of the initial turns out:
Best regards.
