CHM 104 1st Edition Lecture 1 Outline of Current Lecture II Math Review III Syllabus Current Lecture CHM 104 Description CHM103 focused on the language of chemistry such as balancing equations unit conversion structure of matter periodic table trends etc CHM104 Will apply this language to one major theme Chemical Change Reactants Products Chapter 13 Change with time How does the molecular world change with time Thermal energy heat causes constant molecular motion Leads to Molecules constantly colliding Some collisions cause electrons in molecules to rearrange Chemical bonds break form new Chemical bonds Kinetics is the study of how these changes occur over time How does a reaction occur what is the mechanism Chemical Kinetics can be used to understand the how Measuring speed of reaction as a function of reactant concentrations Measuring speed of reaction as a function of temperature These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute By Studying how fast a reaction occurs using a specific set of conditions we can PREDICT how fast it will occur using different conditions Allows for development of more efficient processes for chemical manufacturing Chapter 14 Chemical Equilibrium How far complete a chemical reaction will go Speed Kinetics Extent If Thermodynamics How far to completion Equilibrium Described by Equilibrium Constant K Ratio of product reactant Use K to calculate final Chapters 15 16 Aqueous Chemistry Apply Chemical Equilibrium concepts to reactions Acids Bases Salts Acid Base behavior models Calculate Acidity basicity pH scale pH buffered solutions Salt solubility more complex than simple solubility rules from chapter 4 Chapters 6 17 Thermochemistry Study of Chemical Energy If a reaction will take place and to what extent Measure energy produced consumed in chemical reaction Calorimetry Predict energy produced consumed in chemical reaction Two major thermodynamic properties Enthalpy Entropy Together they dictate whether something will happen Chapter 18 Electrochemistry Electricity generated chemically through redox reaction Separate oxidation reduction Electron transfer through circuit Electrochemistry used to determine how much electricity a reaction produces
