![**Question 5: Calculation of Rate Constant Using Arrhenius Equation**
From the activation energy (Ea) and collision frequency factor (A) that you determined in this experiment, calculate the rate constant at 85 degrees Celsius.
**Instruction:**
To complete this calculation, use the Arrhenius equation given by:
\[ k = A \cdot e^{-\frac{E_a}{RT}} \]
Where:
- \( k \) is the rate constant.
- \( A \) is the collision frequency factor.
- \( E_a \) is the activation energy.
- \( R \) is the universal gas constant (\( 8.314 \, \text{J/mol·K} \)).
- \( T \) is the temperature in Kelvin.
Here, convert the temperature from Celsius to Kelvin using the formula:
\[ T(K) = T(°C) + 273.15 \]
For 85 degrees Celsius:
\[ T = 85 + 273.15 = 358.15 \, \text{K} \]
Substitute the values of \( A \), \( E_a \), \( R \), and \(T \) into the Arrhenius equation to determine the rate constant \( k \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa755e52e-afcf-45db-bf55-07fc4c384d8b%2F760c1a88-09d5-48d2-a4c1-36b62765f349%2Flutxcj5_processed.png&w=3840&q=75)
