WebActivation energy and heat of reaction in a reaction system. If the same reaction is studied with different catalysts or if analogous reactions are compared, it is usually found that the quantities Eact and A of the Arrhenius equations are interrelated. An increase in Eact is then “compensated” by an increase in A according to the equation: (20.10) WebMar 9, 2024 · Glenarden city HALL, Prince George's County. Glenarden city hall's address.
