What is the frequency factor in the Arrhenius equation?
Understand the Problem
The question is asking for the frequency factor in the Arrhenius equation, which relates to chemical reaction rates. The Arrhenius equation expresses how the rate of a reaction depends on temperature and activation energy. The frequency factor represents the number of collisions that result in a reaction, and is a key component in determining the reaction rate.
Answer
The frequency factor in the Arrhenius equation is denoted by 'A'.
The symbol 'A' in the Arrhenius equation denotes the pre-exponential or frequency factor, representing the frequency of correctly oriented collisions that have enough energy to start a chemical reaction.
Answer for screen readers
The symbol 'A' in the Arrhenius equation denotes the pre-exponential or frequency factor, representing the frequency of correctly oriented collisions that have enough energy to start a chemical reaction.
More Information
The Arrhenius equation describes how reaction rate constants change with temperature. 'A,' the frequency factor, helps determine the number of successful collisions.
Tips
A common mistake is to overlook the role of molecular orientation and collision frequency in calculating the frequency factor.
