If the half-life period of a first order reaction in A is 2 minutes, how long will it take [A] to reach `25%` of its initial concentration ?

Explanation

To solve the problem of how long it will take for the concentration of A to reach 25% of its initial concentration in a first-order reaction, we can follow these steps:

### Step 1: Understand the given information
- The half-life (T_half) of the reaction is given as 2 minutes.
- We need to find the time required for the concentration of A to reach 25% of its initial concentration.

### Step 2: Determine the rate constant (k)
For a first-order reaction, the relationship between the half-life and the rate constant (k) is given by the formula:
...
