Under what conditions do nitrogen and hydrogen combine to form ammonia in Haber's process?

Explanation

To determine the conditions under which nitrogen and hydrogen combine to form ammonia in the Haber process, we need to consider both pressure and temperature. Here’s a step-by-step breakdown:

### Step 1: Understanding the Reaction
The Haber process involves the reaction of nitrogen (N₂) and hydrogen (H₂) to produce ammonia (NH₃). The balanced chemical equation for this reaction is:
\[ N_2(g) + 3H_2(g) \rightarrow 2NH_3(g) \]
