Determining Activation Energy - Westfield State …
WebIn general, the transition state of a reaction is always at a higher energy level than the reactants or products, such that E A \text E_{\text A} E A start text, E, end text, start subscript, start text, A, end text, end subscript always has a positive value – independent of whether the reaction is endergonic or exergonic overall. The activation energy shown in … Webwhere k is the rate constant, A is called the Arrhenius pre-exponential constant, Ea is the activation energy, R is the gas constant, and T is the temperature (in units of kelvin). An important point regarding the Arrhenius equation is that the rate constant (k) depends on temperature and on the value of the activation energy (Ea). WebThe Arrhenius equation allows us to calculate activation energies if the rate constant is known, or vice versa. As well, it mathematically expresses the relationships we established earlier: as activation energy term Ea increases, the rate constant k decreases and therefore the rate of reaction decreases.
