Question

The rate constant in an elementary reaction's rate equation can be modeled by the Arrhenius equation: . a. The coefficient A is the frequency factor. What are the units of A for a first-order reaction

Answer 1

For a first-order reaction, the unit of frequency factor (A) is s⁻¹.

What is the Arrhenius equation?

The Arrhenius equation can be used to calculate the rate constant at a given temperature for a first-order reaction. Mathematically the Arrhenius equation is given by:

$Log (\frac{k_2}{k_1} )=\frac{E_a}{2.303R} [\frac{1}{T_1} -\frac{1}{T_2}]$

For a first-order reaction, the unit of frequency factor (A) is s⁻¹ because it has the same unit as the rate constant.
