Using a first order plot, determine the rate constant, k_1, for the oxidation of benzyl alcohol with potassium permanganate at the temperature, T_1 = 20.5 degree C, from the information in the table below. (Molar absorptivity, epsilon = 2350 M_-1 cm_-1; path length, I =1 cm) Using a second rate constant, k_2 = 0.0599 min_-1, at the temperature, T_2 = 37.6 degree C, determine the activation energy, E_a for the oxidation of benzyl alcohol with potassium permanganate. (Gas constant, R = 8.314 J/(K middot mol))
