The half life for a given reaction was doubled as the initial concentration of a reactant was doubled. What is the order of reaction.

Explanation

To determine the order of the reaction based on the relationship between half-life and initial concentration, we can follow these steps:

### Step 1: Understand the relationship between half-life and concentration for different orders of reactions.
- **Zero Order Reaction**: The half-life (t₁/₂) is given by the formula:
\[ t_{1/2} = \frac{[A]_0}{2k} \]
This indicates that half-life is directly proportional to the initial concentration \([A]_0\).
