The rate constant of a first order reaction is `1.54×10^(−3)sec^(−1)` . Calculate its half life period.

Explanation

To calculate the half-life period of a first-order reaction given the rate constant (k), we can use the formula for the half-life of a first-order reaction:

\[ t_{1/2} = \frac{0.693}{k} \]

**Step 1: Identify the value of k.**
The rate constant \( k \) is given as \( 1.54 \times 10^{-3} \, \text{sec}^{-1} \).
