The following data were obtained at a certain temperature for the decomposition of ammonia in contact with tungsten:
p (m m Hg) 50 100 200
Relative `t_(1//2)` 3.64 1.82 0.91
Find the order of the reaction.

Explanation

To determine the order of the reaction for the decomposition of ammonia in contact with tungsten, we will analyze the provided data on pressure and relative half-lives.

### Step-by-Step Solution:

1. **Understanding the Relationship**:
The half-life (\( t_{1/2} \)) for a reaction of order \( n \) is given by the formula:
\[
t_{1/2} = \frac{2^{n-1}}{k \cdot n} \cdot \frac{1}{[A_0]^{n-1}}
