thnewort4 ±Applying the Colisor, Model s previous 1 6 of 11 next. ± Applying the Collision Model The comect ranking cannot be determined In the collision model it is assumed that reactions occur as a result of collisions between molecules with the correct kinetic energy and orientation. The minimum energy required for a reaction to occur when molecules collide is called the activation energy. E The number of collisions that are favorably orienbed for a reaction is descibed by the frequency factor, A The Ahenius equation relates both of these factors to the rate constant, k Submit My Answers Give Up Correct The activation energy, E. for a reacion is Ike a barrier that must be overcome for the reaction to occur The frequency factor A, is the fraction of collisions that are tavorably oriented Fraction of molecules where R8.314 J/(mol - K) and T is the emperature in kelvins The exponertial term in the Arthenius equation is oqual to the fraction of molecules.
