Question

3 104 m1 s1 at 100c, and 1.3 103 m1 s1 150c, what is the energy of activation (ea ) (in kj) for this reaction

Answer 1

There are instances where the activation energy can be negative. There are reactions where the rate of the reaction decreases with increasing temperatures. ... So when you fit the rate constant into an Arrhenius expression, it results in a negative activation energy.
