The half-life gets longer as the initial concentration increases in zero-order reaction.
The amount of time it takes for the concentration of a given reactant to reach 50% of its initial concentration is known as the half-life of a chemical reaction (i.e. the time taken for the reactant concentration to reach half of its initial value).
For zero order reaction:
The half-life is given as:
![t_{1/2}=\frac{[A]_{0}}{2k}](https://tex.z-dn.net/?f=t_%7B1%2F2%7D%3D%5Cfrac%7B%5BA%5D_%7B0%7D%7D%7B2k%7D)
where k is the rate constant of the reaction and ![[A]_{0}](https://tex.z-dn.net/?f=%5BA%5D_%7B0%7D)
is the initial concentration.
As we can see that the half-life is directly proportional to the initial concentration. Therefore, when the initial concentration increases the half-life gets longer.
For the first-order reaction,
The half-life is given as:
A first-order reaction's half-life is independent of the initial concentration.
For a second-order reaction,
The half-life is:
![t_{\frac{1}{2} }=\frac{1}{k[A]_{0}}](https://tex.z-dn.net/?f=t_%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%3D%5Cfrac%7B1%7D%7Bk%5BA%5D_%7B0%7D%7D)
The initial concentration is inversely proportional to the half-life, so when the initial concentration increases the half-life will get shorter.

This problem is providing us with the maximum mass of Imitrex a patient can get daily as 0.2 g. Also, the mass of a tablet is given as 25 mg so the number of tablets they get in a day is required. After the calculations, the result turns out to be 10 tablets.
<h3>Dimensional analysis:</h3>
In chemistry, dimensional analysis is used to calculate specific outcomes given useful information to do so. Despite not having specific formulas for every problem, one can come up with a feasible proportional-factor-based setup, in order to obtain the required.
In this case, since the mass per tablet is 25 mg, one can divide the maximum dosage by this mass per tablet, both in grams, to obtain the required number of tablets for a daily dosage:
