The conversion of cyclopropane, an anesthetic, to propylene has a rate constant k - 1.3x10?6 s?1 at 400°C and k = 1.1x10?5 s?1 at 430°C. a) What is the activation energy in kJ mol?1? b) What is the value of the frequency factor, A, for this reaction? I'm having problem with finding the activation evergy and when to use exp on my calculator.
