The correct Answer is:
To find the temperature coefficient of the reaction based on the given equation for the variation of the rate constant with temperature, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Given Equation**: The equation provided is: \[ \ln k_T = \ln k_0 + \frac{\ln 3}{10} T \] where \( k_T \) is the rate constant at temperature \( T \) and \( k_0 \) is the rate constant at a reference temperature (usually 0°C). 2. **Identify the Temperature Coefficient Formula**: The temperature coefficient \( \mu \) is defined as: \[ \frac{k_T}{k_0} = \mu^{(T - 0)} \] This can be rearranged to: \[ \ln k_T - \ln k_0 = (T - 0) \ln \mu \] 3. **Rewrite the Given Equation**: From the given equation, we can express the left-hand side: \[ \ln k_T - \ln k_0 = \frac{\ln 3}{10} T \] 4. **Set the Two Equations Equal**: Now we can equate the two expressions we have for \( \ln k_T - \ln k_0 \): \[ \frac{\ln 3}{10} T = T \ln \mu \] 5. **Cancel \( T \) from Both Sides**: Assuming \( T \) is not zero (since \( T \geq 0 \)), we can divide both sides by \( T \): \[ \frac{\ln 3}{10} = \ln \mu \] 6. **Solve for \( \mu \)**: To find \( \mu \), we exponentiate both sides: \[ \mu = e^{\frac{\ln 3}{10}} = 3^{\frac{1}{10}} \] 7. **Final Result**: The temperature coefficient \( \mu \) is: \[ \mu = 3^{0.1} \] ### Conclusion: The value of the temperature coefficient of the reaction is \( 3^{0.1} \).
