Problem- What is the Ea of a reaction in which a first rate constant and temperature are 0.000288 L/mol/s and 595K, and a second rate constant and temperature are 0.00194 L/mol/s and 695K?
Also how is activation energy defined? The difference in what exactly?
It is not a question in the book, so I just need the full solution of deriving!
