There are several factors that affect the rate I Review Cons tants Penodic constant of a reaction. These factors include temperature, activation energy, steric factors (orientation), and also collision frequency, which changes with concentration and phase. All the factors that affect the rate constant can be Part A summarized in an equation called the Arrhenius equation: A certain reaction has an activation energy of 67.0 kJ/mol and a frequency factor of A1 = 3.20x1012 M-'s-. What is the rate constant, k, of this reaction at 20.0 °C ? k = Ae-E./RT where k is the rate constant, A is the frequency factor, E, is the activation energy, R= 8.314 J/(mol - K) is the universal gas constant, and T is the absolute temperature. Express your answer with the appropriate units. Indicate the multiplication of units explicitly either with a multiplication dot (asterisk) or a dash. • View Available Hint(s) Figure 1 of 1 HA 1 k = 2.7 • 10 M1 s 1 Submit Previous Answers slope - In k X Incorrect; Try Again; 5 attempts remaining The linear form of the Arrhenius equation The Arrhenius equation can be rearranged to a form that resembles the equation for a straight line: 1/T
