Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Introduction of Equilibrium In our daily life, we observe several chemical and physical changes. For example, a banana gets ripened after few days, silver gets tarnished in few months and iron gets rusted slowly. These processes proceed in one direction. Now let … [Read more...] about Introduction of Equilibrium

Third Law of Thermodynamics
Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Third Law of Thermodynamics The entropy of a substance varies directly with temperature. Lower the temperature, lower is the entropy. For example, water above 100° C at one atmosphere exists as a gas and has higher entropy (higher disorder). The water molecules are … [Read more...] about Third Law of Thermodynamics
Gibbs Free Energy
Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Gibbs Free Energy One of the important applications of the second law of thermodynamics is to predict the spontaneity of a reaction under a specific set of conditions. A reaction that occurs under the given set of conditions without any external driving force is … [Read more...] about Gibbs Free Energy
Second Law of Thermodynamics
Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Second Law of Thermodynamics Need for the Second Law of Thermodynamics: We know from the first law of thermodynamics, the energy of the universe is conserved. Let us consider the following processes: 1. A glass of hot water over time loses heat energy to the … [Read more...] about Second Law of Thermodynamics
Latice Energy (ΔHlattice)
Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Latice Energy (ΔHlattice) Lattice energy is defined as the amount of energy required to completely remove the constituent ions from its crystal lattice to an infinite distance from one mole of crystal. It is also referred as lattice enthalpy. NaCl(s) → Na+(g) + … [Read more...] about Latice Energy (ΔHlattice)
