Final answer:
The pattern in the given chemical reaction 2 NO2(g) → N2O4(g) is the conversion of two molecules of nitrogen dioxide (NO2) to one molecule of dinitrogen tetroxide (N2O4). This reaction is an example of a reversible reaction.
Step-by-step explanation:
The pattern in the given chemical reaction 2 NO2(g) → N2O4(g) is the conversion of two molecules of nitrogen dioxide (NO2) to one molecule of dinitrogen tetroxide (N2O4). This can be represented as:
- 2 NO2(g) → N2O4(g)
The reaction can also go in the opposite direction, with N2O4 breaking down to form NO2:
- N2O4(g) → 2 NO2(g)
These reactions are examples of reversible reactions, where the reactants can convert into products and vice versa.
