CHEM 1C Chapter Notes - Chapter 15: Reaction Rate Constant, Slow Step, Reaction Intermediate
Document Summary
15. 2 rates of reaction and the particulate nature of matter. (a) the concentration of the reacting particles. (c) the structure and relative orientation of the reacting particles. Greater number of particles in a given volume more concentration the greater the number of collisions there are per unit time. Rate depends on the initial amount of reactant: greater initial amount, the faster the initial rate. Fast reaction rate: high temperatures (many particle collisions occur with enough energy to break initial bond) Slow reaction rate: low temperatures (very few collisions) The structure and orientation of the colliding particles. First reaction has two ways b can collide with. Second reaction, b can only react on one of the sides. All other factors being equal, the first reaction would have a faster rate. Orientation of the initial reactants determine the reaction rate. 15. 3 defining and measuring the rate of a chemical reaction. Fast rate: large fraction of molecules reacts to form products.
