The formation of `NH_3` is exothermic. What is the effect of heating the system ?

Explanation

To analyze the effect of heating on the formation of ammonia (NH₃), we need to consider the nature of the reaction and its thermodynamic properties.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
The formation of ammonia from nitrogen (N₂) and hydrogen (H₂) can be represented by the balanced equation:
\[
N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)
