During 1920S, M. Trautz, W. Lewis, C. Hinshelwood et al. finally established a theory based on the collision which is called the simple collision theory. A reaction can take place only if the molecules of the reactants collide. Therefore, the rate constant of the reaction may be predicted by calculation of the collision frequency of the reactants

The fundament of sct The premise of reaction is the collision between reactants The reaction rate of reaction is proportional to the collision frequency (么); Not all the collision is effective. The collision can be either non-reactive (elastic) collision or reactive couision Only the molecules posses energy excess to a critical value(e can lead to reactive collision
