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⋅K) is the universal gas constant, and T is the absolute temperature. __________________________________________________ A certain...
