The rate constant of a certain reaction is known to obey the Arrhenius equation, and to have an activation energy E=72.0 kJ/mol. If the rate constant of this -1 reaction is 3.4 × 10² M¹s at 308.0 °C, what will the rate constant be at 218.0 °C? Round your answer to 2 significant digits. k = -1 -1 S x10 ?
