Question

The activation energy of a reaction is 9kcal/mol the increase in rate constant when temperature is raised form 295 to 300 k is

Answer 1

Explanation:

Yes a reaction can have zero activation energy. Process with zero activation energy most commonly involve the combination of oppositively charged ions or the pairing up of electron in free radicals. For ex- dimerization of nitric oxide(NO2) to N2O4 which is an odd electron molecule have zero activation energy.
