Question- Chemists commonly use a rule of thumb that an increase of 10 K in temperature doubles the rate of a reaction. What must the activation energy be for this statement to be true for a temperature increase from 18°C to 28°C?
It is not a question in the book, so I just need the full solution of deriving!
