The half life of a first order reaction is `60 min`. How long will is take to consume `90%` of the reactant?

Explanation

To solve the problem of how long it will take to consume 90% of the reactant in a first-order reaction with a half-life of 60 minutes, we can follow these steps:

### Step-by-Step Solution:

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