(You must manipulate the data before making the graph.) See excel file on my website. Use the activation energy and frequency factor determined from the graph and the Arrhenius equation to calculate the rate constant for the reaction at 85 C. slope = -Ea/R-12459 K = -Ea/8.314 J/mol-K. Ea = 103584 J/mol = 104 kJ/mol. y-intercept = ln A = 31.6 ................
