In other words, we isolate the pre-exponential term equivalent in the collision frequency formula. 3.2.1 Reaction Rate According to the Collision Theories According to collision theories, the rate of a chemical reaction will directly be affected by the following 3 WebFeb 19, 2016 · So just solve for the activation energy. So we have 3.221 times 8.314 and then we need to divide that by 1.67 times 10 to the -4. And so we get an activation energy of approximately, that would be 160 kJ/mol. We need our answer in kJ/mol and not J/mol, so we'll say approximately 160 kJ/mol here. data type for float in sqlThe Arrhenius law predicts that the motion of the structural units (atoms, molecules, ions, etc.) should slow down at a slower rate through the glass transition than is experimentally observed. In other words, the structural units slow down at a faster rate than is predicted by the Arrhenius law.
