## Frequency Factor Formula

The following formula is used to calculate the Frequency Factor.

**FF = K / (e^(-Ea/(R*T)))**

Variables:

- FF is the Frequency Factor ( )
- K is the reaction rate constant
- Ea is the energy of activation (J)
- T is the temperature (K)

## How to Calculate Frequency Factor?

The following steps outline how to calculate the Frequency Factor.

- First, determine the reaction rate constant.
- Next, determine the energy of activation (J).
- Next, determine the temperature (K).
- Next, gather the formula from above = FF = K / (e^(-Ea/(R*T))).
- Finally, calculate the Frequency Factor.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

reaction rate constant = 148

energy of activation (J) = 541

temperature (K) = 512FF = K / (e^(-Ea/(R*T))) =** ** ?
