E1.1 Arrhenius Equation

Example 1.1: Find the reaction rate constant at 25 °C if the following data apply:

Frequency factor = 8 ´ 10¹⁴ s^-1

Energy of activation is 1.39 ´ 10⁴ cal/mol

Solution

Gas law constant, R = 1.987 cal/(mol·°K)

Frequency factor, A = 8 ´ 10¹⁴ s^-1

Temperature, T = 298.15 °K

Energy of activation, E = 1.39 ´ 10⁴ cal/mol

Reaction rate constant, k (Equation 1.1):
