The activation energy of a certain reaction is 37.9kJ/mol. At 20C, the rate constant is 0.0170s1. At what temperature in degrees Celsius would this reaction go twice as fast? Express your answer with the appropriate units. Given that the initial rate constant is 0.0170s1 at an initial temperature of 20C, what would the rate constant be at a temperature of 170 . C for the same reaction described in Part A? Express your answer with the appropriate units
