# Thermodynamic Properties of an Endothermic Reaction

For the following endothermic reaction:

\[ \text{N}_2(g) + \text{2O}_2(g) \rightarrow \text{2NO}_2(g) \]

Match the thermodynamic properties with their appropriate numerical interpretation.

### Thermodynamic Terms
1. **ΔH<sub>rxn</sub> (Enthalpy change of the reaction)**
2. **ΔS<sub>rxn</sub> (Entropy change of the reaction)**
3. **ΔG<sub>rxn</sub> (Gibbs free energy change of the reaction)**
4. **ΔS<sub>Universe</sub> (Change in entropy of the universe)**

### Numerical Interpretations
1. **> 0**
2. **< 0**
3. **= 0**
4. **> 0 at low T, < 0 at high T**
5. **< 0 at low T, > 0 at high T**

### Instructions
Analyze the reaction characteristics and thermodynamic principles to match each property with its corresponding numerical interpretation. Remember, for endothermic reactions, certain general behaviors in terms of energy and entropy can be assumed:

- **ΔH<sub>rxn</sub>** is typically greater than zero since the reaction absorbs heat.
- **ΔS<sub>rxn</sub>** may vary based on the disorder between reactants and products.
- **ΔG<sub>rxn</sub>** and **ΔS<sub>Universe</sub>** will be influenced by the temperature dependency.

Use this information to correctly identify the sign and behavior of each thermodynamic property in relation to this specific reaction.
