`N_(2) + 3H_(2) to 2NH_(3)`, the rate of disappearance of nitrogen is `0.02 mol L^(-1) s^(-1)`. What is the rate of apperance of ammonia?

Explanation

To solve the problem, we need to determine the rate of appearance of ammonia (NH₃) based on the given rate of disappearance of nitrogen (N₂) in the reaction:

\[ N_2 + 3H_2 \rightarrow 2NH_3 \]

### Step-by-Step Solution:

1. **Identify the Stoichiometry of the Reaction:**
- From the balanced equation, we see that 1 mole of N₂ produces 2 moles of NH₃.
