Learn the rules for ionic compounds

Background: How ionic compounds are formed Ionic compounds are formed from the electrostatic attraction of oppositely charged ions. The ions are arranged in such a way that they form a giant crystal lattice of alternating positive and negative ions. An example of an ionic compound is sodium chloride, NaCl, also commonly known as table salt. […]

Learn the rules for covalent compounds

Covalent compound A covalent compound involves two non-metals forming a chemical structure together.  Rules What are the rules for naming covalent compounds? • Covalent compounds involve multiple non-metals • Covalent compounds use prefixes – to indicate the number of atoms of each element in the compound • The element that further left of the periodic […]

Integrated Rate Laws

Overview There are two types of rate laws that we need to learn for AP chemistry: (1) Differential rate law (2) Integrated rate law What is the difference between the differential rate law and integrated rate law? The differential rate law is actually a derivative of the integrated rate law. In experiments: Differential rate law […]

Differential Rate Laws

Methods for determining order of reaction This section looks at how concentration affects reaction rate. You will learn how to determine the order of a reaction. Reactions are often categorized into first, second, third order, etc. and this information is useful for showing the mathematical relationship between concentrations and rates. Rate laws may be written […]

Rate of reaction

Measuring rate This section aims to cover the following topics: Define chemical reaction rate Define rate expression Relative rates of reaction and stoichiometry ratio Change in concentration over time The rate of a chemical reaction can be thought of as the speed at which a chemical reaction happens and this can be expressed as the […]
