Calculate the activation energy for the reaction 2NOCl = 2NO + Cl, if the rate constant k is equal to 0.286 L/mol*s at 500 K and 0.175 L/mol*s at 490 K.
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...
