Transcribed Image Text:**Data Table:**
| (-rA) | -0.004 | 0.0800 | 1.2000 | 16.00 |
|--------|--------|--------|--------|--------|
| T(K) | 600 | 680 | 760 | 840 |
| ln(K) | -10.203| -7.207 | -4.499 | -1.909 |
| 1/T | 0.00166| 0.00147| 0.00131| 0.00119|
**Converted Data for Plot:**
| 1/T (X-axis) | ln(K) (Y-axis) |
|--------------|----------------|
| 0.00166 | -10.203 |
| 0.00147 | -7.207 |
| 0.00131 | -4.499 |
| 0.00119 | -1.909 |
**Graph Explanation:**
- **Type:** Scatter Plot
- **X-Axis:** Represents the values of 1/T.
- **Y-Axis:** Represents the natural logarithm of K, ln(K).
- **Trendline Equation:** y = -0.0002x
- Indicates a linear relationship with a negative slope.
- **R² Value:** 0.8789
- Suggests a strong correlation between 1/T and ln(K).
- **Data Points:** Four points plotted according to the values in the converted data table.
- **Trendline:** A linear trendline is drawn through the data points with dotted lines indicating the fit.
This graphical representation is typically used in kinetic studies to determine reaction rates and understand temperature dependence of a reaction, often applying the Arrhenius equation.
