# A certain reaction has an activation energy of 69.0kJ/mol and a frequency factor of A1 = 6.60 Times 1012M-ls-1 What is the rate constant, k, of this reaction at 23.0 degree C ? Express your answer with the appropriate units. Indicate the multiplication of units explicitly either with a multiplication dot (asterisk) or a dash. The linear form of the Arrhenius equation The Arrhenius equation can be rearranged to a form that resembles the equation for a straight line: ln k = -(Ea/R) (1/T) + ln A y = m x + b where y is In k, m s the slope or -Ea/R, x is 1/T, and b is the y-intercept or ln A. The linearity of this equation is illustrated graphically in the image.(Figure 1) An unknown reaction was observed, and the following data were collected: Determine the activation energy for this reaction. Express your answer with the appropriate units.
