There are several factors that affect the rate constant of a reaction. These factors include temperature, Templetes 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 Arrhenius equation: Part A k= Ae/r where k is the rate constant, A is the frequency factor, E, is the activation energy, R= 8.314 J/(mol - K) is the universal gas constant, and T is the absolute temperature. A certain reaction has an activation energy of 70.0 kJ/mol and a frequency factor of A1 = 6.10x1012 M-'s 1. What is the rate constant, k, of this reaction at 29.0 °C ?
