previous wrong answers are: 1.3x10^-7, 142.5, and 1.3x10^-4

MISSED THIS? Read Section 15.5; Watch Determine the activation barrier for the reaction. A reaction has a rate constant of 1.27104s1 at 29C Express your answer in units of kilojoules per mole. and 0.230s1 at 75C. Correct The activation energy Ea is an energy barrier or hump that must be surmounted for the reactants to be transformed into products. The activation energy was found using the following equation: ln(k1k2)EaEaEa=REa(T11T21)=(T11T21)Rln(k1k2)=(302K1368K1)8.314modKJln(1.27104s10.25a1)1000J1kJ=143molkJ Part B What is the value of the rate constant at 18C ?
