Many reactions follow Arrhenius behavior. What is the relationship between reaction constant and temperature for Arrhenius behavior?
Homework Answers
Solution:
According to Arrhenius equation:
K = A e -Ea/RT
Where,
K = rate constant, Ea = activation energy, R = gas constant and T = temperature
Therefore, a reaction which shows Arrhenius behavior means, the rate constant of a reaction increases exponentially when the activation energy decreases. Because the rate of a reaction is directly proportional to its rate constant , therefore rate increases exponentially with temperature.

The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins and is typically written as k=Ae−Ea/RT where R is the gas constant (8.314 J/mol⋅K), A is a constant called the frequency factor, and Ea is the activation energy for the reaction. However, a more practical form of this equation is lnk2k1=EaR(1T1−1T2) which is mathmatically equivalent to lnk1k2=EaR(1T2−1T1) where k1 and k2 are the rate constants for a single reaction at two different absolute...

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...
