A first order reaction is found to have a rate constant `k=7.39xx10^(-5)s^(-1)`. Find the half life of this reaction.

Explanation

To find the half-life of a first-order reaction given the rate constant \( k = 7.39 \times 10^{-5} \, \text{s}^{-1} \), we can use the formula for the half-life of a first-order reaction:

### Step-by-Step Solution:

1. **Identify the formula for half-life of a first-order reaction**:
The half-life (\( t_{1/2} \)) of a first-order reaction is given by the formula:
\[
t_{1/2} = \frac{0.693}{k}
