Wednesday 9/6/17 CHAPTER 14: KINETICS Collision Theory: 3 main steps must occur to initiate the reaction 1. For a reaction to occur, two molecules need to collide 2. Energy (kinetic) is needed for bonds to be broken and reformed 3. The molecules must collide in the proper orientation all 3 steps create the rate of reaction increasing concentration increases the number of collisions we can control only the first 2 of the 3 steps to try to control the rate of reaction 14.1 [KINETICS] studying the rate of chemic
