The rate constant of a certain reaction is known to obey the Arrhenius equation, and to have an activation energy E.-28.0 klimol. If the rate constant of this reaction is 14x10 m 's' at 107.0°C, what wil the rate constant be at 205,0 °C? Round your answer to 2 significant digits. k 0.0 X х ?
The rate constant k for a certain reaction is measured at two different temperatures: temperature k 450.0 °C 1.8 x 108 3.2 x 107 356.0 °C Assuming the rate constant obeys the Arrhenius equation, calculate the activation energy E, for this reaction. Round your answer to 2 significant digits. E = 0 mol х 5 ?
