Unformatted text preview: Ae − E a RT (5.1) where E a is the Arrhenious activation energy and A is a constant called the frequency factor. Notice that if one takes the natural log of the Arrhenious equation one has ln k = ln A − E a RT . (5.2) If ln k is plotted versus 1 T we get a straight line whose slope is E a R and intercept is ln A. So one needs to know the rate constant at least two temperatures to determine the Arrhenious parameters. THE ARRHENIOUS EQUATION 23...
