Learn the definition, statement and examples of Le Chatelier's principle, a chemistry principle that predicts the effect of a change in conditions on chemical equilibrium. The principle can also be applied to other systems that respond to stress or disequilibrium.
The Haber process, also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia from nitrogen and hydrogen. It was developed by Fritz Haber and Carl Bosch in the early 20th century and is essential for fertilizers, explosives and other industries.
Learn about the diffusion equation, which describes the movement of particles from high to low concentration, and its applications in various fields. The diffusion equation is derived from Fick's first and second laws, which relate the flux and concentration gradient of diffusing substances.
An equilibrium constant is the value of the reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time. Learn about different types of equilibrium constants, such as formation, association, dissociation, and micro-constants, and how they are related to reaction parameters and Gibbs free energy.
Learn about dissociation, the process of molecules splitting into atoms, ions, or radicals, and its applications in chemistry. Find out how to calculate dissociation constants, degrees, and factors for acids, bases, salts, gases, and receptors.
Learn how solvents can affect solubility, stability, reaction rates and mechanisms in chemistry. Explore the examples of acid-base, keto-enol and Hughes-Ingold rules for different solvents.
Liquid nitrogen is nitrogen in a liquid state at low temperature, produced by fractional distillation of liquid air. It is widely used as a coolant, in cryotherapy, food preparation, astronomy and other applications, but also requires thermal insulation and careful handling due to its low boiling point and expansion ratio.
To provide a rough example of how much pressure this is, to melt ice at −7 °C (the temperature many ice skating rinks are set at) would require balancing a small car (mass ~ 1000 kg [18]) on a thimble (area ~ 1 cm 2). This shows that ice skating cannot be simply explained by pressure-caused melting point depression, and in fact the mechanism ...
