WebJul 19, 2024 · The Arrhenius equation demonstrates the affect of various properties on the rate constant (and consequently, the rate) of a reaction. ... (or frequency factor), A, represents the frequency of effective collisions between molecules that can undergo a chemical change. This factor is determined via experiment and extrapolation. WebBut we know that frequency can be written in terms of speed formula, $$ v = f \cdot \lambda$$ Which can be rearranged into the following, $$ \frac{v}{\lambda} = f $$ If you put that expression into the above equation, then that becomes $$ E = f \cdot \frac{v}{\lambda}$$ Hence the same formula can be written in many ways.
