  2. Thermodynamic versus kinetic reaction control - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_versus...

    Here, the difference in pK b between the base and the enolate is so large that the reaction is essentially irreversible, so the equilibration leading to the thermodynamic product is likely a proton exchange occurring during the addition between the kinetic enolate and as-yet-unreacted ketone. An inverse addition (adding ketone to the base) with ...

  3. Kinetics (physics) - Wikipedia

    en.wikipedia.org/wiki/Kinetics_(physics)

    In physics and engineering, kinetics is the branch of classical mechanics that is concerned with the relationship between the motion and its causes, specifically, forces and torques. [ 1 ] [ 2 ] [ 3 ] Since the mid-20th century, the term " dynamics " (or " analytical dynamics ") has largely superseded "kinetics" in physics textbooks, [ 4 ...

  4. Action principles - Wikipedia

    en.wikipedia.org/wiki/Action_principles

    The energy function in the action principles is not the total energy (conserved in an isolated system), but the Lagrangian, the difference between kinetic and potential energy. The kinetic energy combines the energy of motion for all the objects in the system; the potential energy depends upon the instantaneous position of the objects and ...

  5. Kinetic resolution - Wikipedia

    en.wikipedia.org/wiki/Kinetic_resolution

    In organic chemistry, kinetic resolution is a means of differentiating two enantiomers in a racemic mixture.In kinetic resolution, two enantiomers react with different reaction rates in a chemical reaction with a chiral catalyst or reagent, resulting in an enantioenriched sample of the less reactive enantiomer. [1]

  6. Chemical kinetics - Wikipedia

    en.wikipedia.org/wiki/Chemical_kinetics

    The kinetic isotope effect is the difference in the rate of a chemical reaction when an atom in one of the reactants is replaced by one of its isotopes. Chemical kinetics provides information on residence time and heat transfer in a chemical reactor in chemical engineering and the molar mass distribution in polymer chemistry.

  7. Mechanical energy - Wikipedia

    en.wikipedia.org/wiki/Mechanical_energy

    The kinetic energy, K, depends on the speed of an object and is the ability of a moving object to do work on other objects when it collides with them. [ nb 2 ] [ 8 ] It is defined as one half the product of the object's mass with the square of its speed, and the total kinetic energy of a system of objects is the sum of the kinetic energies of ...

  8. Kinematics - Wikipedia

    en.wikipedia.org/wiki/Kinematics

    Kinematics is a subfield of physics and mathematics, developed in classical mechanics, that describes the motion of points, bodies (objects), and systems of bodies (groups of objects) without considering the forces that cause them to move.

  9. Specific kinetic energy - Wikipedia

    en.wikipedia.org/wiki/Specific_kinetic_energy

    The specific kinetic energy of a system is a crucial parameter in understanding its dynamic behavior and plays a key role in various scientific and engineering applications. Specific kinetic energy is an intensive property, whereas kinetic energy and mass are extensive properties. The SI unit for specific kinetic energy is the joule per ...
