RA Review I Constants 1 Periodic Table Suppose that a certain biologically important reaction is quite slow at physiological temperature (37C) in the absence of a catalyst. Part A Assuming that the collision factor remains the same, by how much must an enzyme lower the activation energy of the reaction in order to achieve a 3x10-fold Increase in the reaction rate? Express your answer in kilojoules per mole to one significant figure. 190 Estayed Estland Submit Request
