+ The Arrhenius Equation: Graphical Method 9 of 11 Review Constants Periodic Table There are several factors that affect the rate constant of a reaction. These factors include temperature, activation energy steric factors (orientation), and also collision frequency, which changes with concentration and phase All the factors that affect the rate constant can be summarized in an equation called the Arthenius equation Part A k=A-E/RT where k is the rate constant. A is the frequency factor, Eis the activation energy...
The Arrhenius equation shows the relationship between the rate constant k and the temperature T in kelvins and is typically written as k=Ae−Ea/RT where R is the gas constant (8.314 J/mol⋅K), A is a constant called the frequency factor, and Ea is the activation energy for the reaction. However, a more practical form of this equation is lnk2k1=EaR(1T1−1T2) which is mathmatically equivalent to lnk1k2=EaR(1T2−1T1) where k1 and k2 are the rate constants for a single reaction at two different absolute...

There are several factors that affect the rate of a reaction. These factors include temperature, activation energy, steric factors (orientation), and also collision frequency, which changes with concentration and phase. All the factors that affect reaction rate can be summarized in an equation called the Arrhenius equation: k=Ae−Ea/RT, where k is the rate constant, A is the frequency factor, Ea is the activation energy, R=8.314 J mol−1 K−1 is the gas constant, and T is the absolute temperature.
