Stoichoimetry , Thermodynamics Periodic Trends , Atomic and Molecular Structure , Gas Laws , and Intermolecular Forces , Equilibria , Kinetics , and Structural Chemistry Qualitative and Quantitative analysis Stoichiometry : This field studies the rates of chemical processes as a function of the concentration of the reacting species , of the products of the reaction , of catalyst and inhibitors , of various solvent media of temperature , and of all other variables that can affect the reaction rate . It is an essential part of the study of chemical kinetics to seek to [banner_entry_middle]

relate the precise fashion in which the reaction rate varies with time to the molecular nature of the rate-controlling inter molecular collision involved in generating the reaction products . Most reactions involve a series of stepwise processes , the sum of which corresponds to the overall observe reaction proportions (or stoichiometry ) in which the reactants combine and the products form only one of the steps , however is generally the rate-controlling one , the others being much faster . By determining the nature of the rate-controlling process from the mathematical analysis of the reaction kinetics and by investigating how the reaction conditions (for instance , solvent , other species , and temperature affect this step , or cause some other process to become the rate controlling one , the physical chemist can deduce the mechanism of reaction .

Code Page 2 Thermodynamics : A field of Physics that describes and correlate properties of macroscopic systems of matter and energy . The principles of thermodynamics are of fundamental importance to all branches of science and engineering .

Periodic Trends (or table : Table of chemical elements arranged to illustrate patterns of recurring chemical and physical processes Elements , such as oxygen , iron , and gold , are the most basic chemical substances and cannot be broken down by chemical reactions . All other substances are formed from combinations of elements . The Periodic Table provides a means of arranging all the known elements and even those yet to be discovered .

Atomic Structure : Atoms are made of smaller particles , called electrons protons , and neutrons . An atom consists of a cloud of electrons surrounding a small , dense nucleus of protons and neutrons . Electrons and neutrons have a property called electric charge , which affects the way they interact with each other and with other electrically charged particles .

Code Page 3 Molecular Structure : Molecular crystals are compounds in which molecules are held together in a crystal lattice by weak intermolecular attractive forces . These crystals do not form a complete network . Because of the weak attractions between the molecules , molecules have low melting temperatures ( typically well below room temperatures ) and are relatively soft . Most molecular organic (carbon containing ) and inorganic compounds form molecular crystals . Examples , include ice solid sulfur dioxide , and solid carbon dioxide .
