1. Calculate the activation energy, Ea, in kilojoules per mole for a reaction at 73.0 ∘C that has a rate constant of 0.278 s−1 and a frequency factor of 9.74×1011 s−1. Ea= kJ/mol 2. Nitogen dioxide, NO2, is a red-brown gas that is considered an air pollutant. When heated, nitogen dioxide gas decomposes into nitrogen monoxide and oxygen gas, according to the following reaction. 2NO2(g)−⇀↽−2NO(g)+O2(g) A sample of nitrogen dioxide in a sealed vessel was heated to 575 K, and...
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...
