Best ResponseYou've already chosen the best response.2E=RT ln (k/A) 40.5 = 0.08206(295.15) ln (0.0130/A) e^(40.5/(0.08206(293.15))) = 0.0130/A 0.07000234854... approx = A use A to solve for k at 100C (373.15 K): 40.5=RT ln (k/A) 40.5=0.08206(373.15) ln (k/30/0.07000234854) 40.5/(0.08206(373.15))=ln (k/30/0.07000234854) e^(40.5/(0.08206(373.15)))=k/0.07000234854 k=0.2627397387 pls. double check my calculations :))

Best ResponseYou've already chosen the best response.2the rate constant should be at least close to 0.0130s^1. not geater than 1.
