1. A reaction in which the pre-exponential term is independent of temperature is found to be a 100 times faster at 200 °C than it is at 25 °C. Calculate the activation energy of the reaction. What will be the reaction rate at 1000 °C?
2. A chemical reaction is found to be 15 times faster at 100 °C than at 25 °C. Measurements show that the pre-exponential term contains temperature to the power of 0.7. Calculate the activation energy of the reaction. What will be the reaction rate at 700 °C?
