simple notes:

In a chemical reaction chemical equilibrium is defined as the state at which there is no further change in concentration of reactants and products.
For example,

At equilibrium, the rate of forwarding reaction is equal to the rate of backward reaction. Equilibrium mixture: The mixture of reactants and products in the equilibrium state is called an equilibrium mixture.
Based on the extent to which the reactions proceed to reach the state of equilibrium, these may be classified into three groups:
(i) The reactions proceed almost to completion and the concentrations of the reactants left are negligible.
(ii) The reactions in which most of the reactants remain unchanged, i.e. only small amounts of products are formed.
(iii) The reactions in which the concentrations of both the reactants and products are comparable when the system is in equilibrium

Chemical Kinetics class 12

Chemical Kinetics name of the chapter: Chemical Kinetics Content Provider: FIITJEE Lecturer from FIITJEE Introduction based on NCERT: Chemistry, by its very nature, is concerned with change. Substances with well-defined properties are converted by chemical reactions into other substances with different properties. For any chemical reaction, chemists try to find out (a) the feasibility of a chemical reaction which can be predicted by thermodynamics ( as you know that a reaction with ΔG < 0, at constant temperature and pressure is feasible); (b) the extent to which a reaction will proceed can be determined from chemical equilibrium; (c) speed of a reaction i.e. time taken by a reaction to reach equilibrium. Along with feasibility and extent, it is equally important to know the rate and the factors controlling the rate of a chemical reaction for its complete understanding. For example, which parameters determine how rapidly food gets spoiled? How to design a rapid...

Periodic Table Shortcut

Periodic table shortcut Name of the page: shortcut for periodic table Done by: FIITJEE Student Applicable for all the classes What is a Periodic Table? a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns. The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. who invented the periodic table? many collections of scientists invented it. Embedded PDF:

Solid state class 12 Physical

Solid states name of the chapter: Solid State Content Provider: FIITJEE Lecturer from FIITJEE Introduction given by NcertText book: We are mostly surrounded by solids and we use them more often than liquids and gases. For different applications, we need solids with widely different properties. These properties depend upon the nature of constituent particles and the binding forces operating between them. Therefore, the study of the structure of solids is important. The correlation between structure and properties helps in discovering new solid materials with desired properties like high-temperature superconductors, magnetic materials, biodegradable polymers for packaging, biocompliant solids for surgical implants, etc. From our earlier studies, we know that liquids and gases are called fluids because of their ability to flow. The fluidity in both of these states is due to the fact that the molecules are free to move about. On the contrary, the constitu...
