Q: What is used to convert concentrations to collisions per second?


Read this paragraph and choose the correct option from the provided answers:

The frequency factor is used to convert concentrations to collisions per second. Equation 14.39 is known as the Arrhenius equation and summarizes the collision model of chemical kinetics, where T is the absolute temperature (in K) and R is the ideal gas constant [8.314 J/(K·mol)]. Ea indicates the sensitivity of the reaction to changes in temperature. The reaction rate with a large Ea increases rapidly with increasing temperature, whereas the reaction rate with a smaller Ea increases much more slowly with increasing temperature. If we know the reaction rate at various temperatures, we can use the Arrhenius equation to calculate the activation energy. Taking the natural logarithm of both sides ofEquation 14.39, Equation 14.40.

 Choices:

- speeds factor

- collision meter

- particles factor

- frequency factor


A:
frequency factor
