WebA typical plot used to calculate the activation energy from the Arrhenius equation. In this graph the gradient of the line is equal to -Ea/R. Extrapolation of the line to the y axis gives an intercept value of lnA. When the temperature is increased the term Ea/RT gets smaller. This means in turn, that the term e-Ea/RT gets bigger. WebActivation energy. Temperature is a measure of the average kinetic energy of the particles in a substance. The activation energy is the minimum energy required for a reaction to occur. This means ...

WebThe Arrhenius equation is k = Ae^(-Ea/RT), where A is the frequency or pre-exponential factor and e^(-Ea/RT) represents the fraction of collisions that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea) at temperature T.This equation can be used to understand how the rate of a … WebJun 1, 2014 · 16.3.2 Determine activation energy (Ea) values from the Arrhenius equation by a graphical method.Note that in the exam, you will be given the graph already p...
