3. The rate of a second-order reaction was measured over temperature range from 700-1000 K. The rate constants are in the table below. Use an Arrhenius plot to find the activation energy and the pre-exponential factor for this reaction. Report your answers to three significant figures, and include units. T(K) 700 730 760 790 810 840 910 1000 k (mol L³¹ s¹) 0.011 0.035 0.105 0.343 0.789 2.17 20.0 145
