Answer:
Explanation:
We can use the Arrhenius equation to relate the activation energy and the rate constant, k, of a given reaction:
k=Ae−Ea/RT
In this equation, R is the ideal gas constant, which has a value 8.314 J/mol/K, T is temperature on the Kelvin scale, Ea is the activation energy in joules per mole, e is the constant 2.7183, and A is a constant called the frequency factor, which is related to the frequency of collisions and the orientation of the reacting molecules.
Both postulates of the collision theory of reaction rates are accommodated in the Arrhenius equation. The frequency factor A is related to the rate at which collisions having the correct orientation occur. The exponential term,
e−Ea/RT, is related to the fraction of collisions providing adequate energy to overcome the activation barrier of the reaction.
