If the rate constant k of a reaction doubles when the temperature increases from 111 °C to 289 °C, what is the activation energy of the reaction in units of kJ/mol? Do not enter units with your numerical answer. Do not use scientific notation.
In going from room temperature (25 C) to 10 C above room temperature, the rate of reaction doubles. Calculate the activation energy for the reaction .
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 k=Ae−Ea/RT where k is the rate constant, A is the frequency factor, Ea is the activation energy, R = 8.3145 J/(K⋅mol) is the gas constant, and T is the...
