If the rate of a reaction gets doubled as the temperature is increased from `27^@ " to " 37^@C`. Find the activation energy of reaction?

Text Solution

AI Generated Solution

To find the activation energy (Ea) of the reaction given that the rate doubles when the temperature increases from 27°C to 37°C, we can use the Arrhenius equation and the concept of the rate constant. ### Step-by-Step Solution: 1. **Convert temperatures from Celsius to Kelvin**: - \( T_1 = 27°C = 27 + 273 = 300 \, K \) - \( T_2 = 37°C = 37 + 273 = 310 \, K \) ...
