Given the following balanced equation, determine the rate of reaction with respect to [N2].
N2(g) + 3 H2(g) → 2 NH3(g)


In the given balanced chemical equation:

\[
\text{N}_2(g) + 3 \text{H}_2(g) \rightarrow 2 \text{NH}_3(g)
\]

The rate of reaction with respect to nitrogen \([N_2]\) is defined as the change in concentration of \(N_2\) over time. Since the stoichiometry of the reaction involves one mole of nitrogen reacting with three moles of hydrogen to produce two moles of ammonia, we can express the rate of reaction in terms of nitrogen as:

\[
\text{Rate} = -\frac{d[\text{N}_2]}{dt}
\]

The negative sign indicates that the concentration of nitrogen is decreasing as the reaction proceeds.

### Relative Rates of Other Species:
- For \( \text{H}_2 \), the rate of reaction is:

  \[
  \text{Rate} = -\frac{1}{3} \frac{d[\text{H}_2]}{dt}
  \]

- For \( \text{NH}_3 \), the rate of reaction is:

  \[
  \text{Rate} = \frac{1}{2} \frac{d[\text{NH}_3]}{dt}
  \]

All of these rates are related through the stoichiometric coefficients of the balanced equation.
