What is Frequency Factor?

The frequency factor, also known as the pre-exponential factor, is a term in the Arrhenius equation that represents the frequency of collisions between reactant molecules. It is used to describe the rate at which a chemical reaction occurs. The frequency factor is influenced by the orientation and energy of the reacting molecules and is crucial for understanding reaction kinetics.

Example Calculations

Example 1:

Using the formula:

\[ FF = \frac{1.5}{e^{\left( -\frac{50000}{8.314 \cdot 298} \right)}} \approx 8.72 \times 10^{8} \]

Example 2:

Using the formula:

\[ FF = \frac{2.0}{e^{\left( -\frac{60000}{8.314 \cdot 310} \right)}} \approx 2.58s \times 10^{10} \]
