To use the Arrhenius equation to calculate the activation energy. As temperature

Question

To use the Arrhenius equation to calculate the activation energy. As temperature rises, the average kinetic energy of molecules increases. In a chemical reaction, this means that a higher percentage of the molecules possess the required activation energy, and the reaction goes faster. This relationship is shown by the Arrhenius equation where is the rate constant, is the frequency factor, is the activation energy, = 8.3145is the gas constant, and is the Kelvin temperature. The following rearranged version of the equation is also useful: where is the rate constant at temperature , and is the rate constant at temperature . The rate constant of a chemical reaction increased from 0.100 to 2.90 upon raising the temperature from 25.0 to 47.0 . Calculate (1/T2-1/T1)

Explanation / Answer

Mention the unit of temperatures 25.0 and 47.0 whether *C or K.

Well if it is in K, just plug in and calculate (1/T2-1/T1) and if it is in *C, convert into Kelvin and then calcualte.
