**Problem 3: Determining ΔH and ΔS from Equilibrium Constants**

The following equilibrium constants (Keq) were measured for a chemical reaction at varying temperatures. Calculate the enthalpy change (ΔH) and entropy change (ΔS) for the reaction, showing all your calculations.

| Keq | Temp (K) |
|-----------|----------|
| 81124361 | 280 |
| 60326116 | 290 |
| 45754713 | 300 |
| 35327486 | 310 |
| 27721059 | 320 |

**Instructions:**

1. Use the van 't Hoff equation to determine ΔH and ΔS.
2. Plot the natural logarithm of Keq (ln(Keq)) against the inverse temperature (1/T) for a linear relationship.
3. The slope of the line will help determine ΔH, and the intercept will help find ΔS.

**Considerations:**

- Remember to convert all temperatures to Kelvin.
- Ensure that your calculations for ln(Keq) and 1/T are accurate.
- Reflect on the linear plot to determine the relationship between Keq and temperature.
