The Arrhenius equation is written as k = Ae^‑Ea/RT, where k, A, and Ea are referred to as the rate constant, pre-exponential factor, and apparent activation energy, respectively.
Reply to 1# yunzhongzi112: The Arrhenius equation is written as k = Ae^‑Ea/RT, where k, A, and Ea are referred to as the rate constant, pre-exponential factor (also known as frequency factor), and apparent activation energy, respectively. R is the molar gas constant, and T is the thermodynamic temperature. An empirical formula for the relationship between the rate constant of chemical reactions and temperature. Its other form is also commonly used: lnk=lnA—Ea／RT. Using this equation, a plot of lnk versus 1/T for the experimental data yields a straight line; the apparent activation energy Ea can be obtained from the slope, while the pre-exponential factor A can be obtained from the intercept
