Given the following Values, what would the Ea be?

What are the constituent metals of stainless steel?

What causes the appearance of lines in a emission spectrum

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?
