What are the products formed when ammonia reacts with excess chlorine ?

Options

A. `N_2 and NCl_3`
B. `N_2 and HCl`
C. `N_2 and NH_4Cl`
D. `NCl_3 and HCl`

Answer

To determine the products formed when ammonia (NH₃) reacts with excess chlorine (Cl₂), we can follow these steps:

### Step 1: Write the initial reaction
When ammonia reacts with chlorine, the initial reaction can be represented as:
\[ \text{2 NH}_3 + \text{3 Cl}_2 \rightarrow \text{N}_2 + \text{6 HCl} \]

### Step 2: Identify the products
From the initial reaction, we see that nitrogen gas (N₂) and hydrogen chloride (HCl) are produced. However, since we are considering the reaction with excess chlorine, we need to look further.

### Step 3: Consider the reaction with excess chlorine
In the presence of excess chlorine, ammonia can further react to form nitrogen trichloride (NCl₃) and hydrogen chloride (HCl). The balanced equation for this reaction is:
\[ \text{NH}_3 + \text{Cl}_2 \rightarrow \text{NCl}_3 + \text{HCl} \]

### Step 4: Combine the reactions
When we consider the complete reaction with excess chlorine, we can summarize it as:
\[ \text{8 NH}_3 + \text{3 Cl}_2 \rightarrow \text{NCl}_3 + \text{6 HCl} \]

### Step 5: Final products
Thus, when ammonia reacts with excess chlorine, the primary products formed are nitrogen trichloride (NCl₃) and hydrogen chloride (HCl).

### Conclusion
The final answer is that the products formed when ammonia reacts with excess chlorine are nitrogen trichloride (NCl₃) and hydrogen chloride (HCl).
