Document Summary
Chapter 2 - structure and reactivity page 49 - page 94. Kinetics and thermodynamics of simple chemical processes page 50 - page 56. Chemical thermodynamics deals with changes in energy that take place when processes occur. Thermodynamics controls extent to which reaction goes to completion. Chemical kinetics deals with velocity or rate at which concentrations of reactants and products change. Kinetics describes speed at which reaction goes to completion. Thermodynamic control - conditions under which the most stable several possible reaction products forms to the greatest extent. Kinetic control - conditions under which the major product of a reaction is the one that forms fastest. Equilibria are governed by the thermodynamics of chemical change. Equilibrium - the state of a reaction at which the concentrations of reactants and products no longer change. Found by product of product concentrations divided by product of reaction concentrations. Large k means reaction has large driving force.
