how to calculate activation energy from arrhenius equation

The Arrhenius equation relates the activation energy and the rate constant, k, for many chemical reactions: How do you solve the Arrhenius equation for activation … A. This Demonstration considers the effect of temperature on the rate of processes obeying the Arrhenius equation, specifically chemical reaction rates and fluid viscosity. We can graphically determine the activation energy by manipulating the Arrhenius equation to put it into the form of a straight line. Posted by on … Here, A is a constant for the frequency of particle collisions, Ea is the activation energy of the reaction, R is the universal gas constant, and T is the absolute temperature. We need to look at how e - (EA / RT) changes - the fraction of molecules with energies equal to or in excess of the activation energy. This equation was first introduced by Svente Arrhenius in 1889. How do you rearrange Arrhenius equation for activation energy? K)], and Ta = absolute temperature (K). off-white dunks orange.
