8. The rate constant of a reaction is measured at different temperatures. A plot of the natural log of the rate constant as a function of the inverse of the temperature (in kelvins) yields a straight line with a slope of -9.74 × 10³ K. What is the activation energy (Ea) for the reaction?
(A) -81 kJ/mol
(B) 81 kJ/mol
(C) 1.2 kJ/mol
(D) -1.2 kJ/mol
(E) 1.2 kcal/mol
