Chemical Reactions - Autocatalytic Reactions
... Autocatalytic reactions are those in which at least one of the products is a reactant ... Perhaps the simplest autocatalytic reaction can be written with the rate equations ... This reaction is one in which a molecule of species A interacts with a molecule of species B ...
Principle Of Maximum Work - Thermochemistry
... or Helmholtz free energy is essentially the energy of a chemical reaction "free" or available to do external work ... “affinity” used by chemists of olden days to describe the “force” that caused chemical reactions ... According to Nobelist and chemical engineering professor Ilya Prigogine “as motion was explained by the Newtonian concept of force, chemists wanted a similar concept of ‘driving force’ for chemical ...
Transition State Theory - Applications of TST: Enzymatic Reactions
... Enzymes catalyze chemical reactions at rates that are astounding relative to uncatalyzed chemistry at the same reaction conditions ... more steps, all of which occur within the few milliseconds that characterize typical enzymatic reactions ... The original proposals of absolute reaction rate theory for chemical reactions defined the transition state as a distinct species in the reaction coordinate that determined the ...
Chemical Plant - Units and Fluid Systems
... Vessels in chemical plants are often cylindrical with rounded ends, a shape which can be suited to hold either high pressure or vacuum ... Chemical reactions can convert certain kinds of compounds into other compounds in chemical reactors ... Chemical reactors may be packed beds and may have solid heterogeneous catalysts which stay in the reactors as fluids move through ...
Cricket (insect) - Cricket Chirping
... This equation describes the activation energy or threshold energy required to induce a chemical reaction ... instance, crickets, like all other organisms, have many chemical reactions occurring within their bodies ... rises, it becomes easier to reach a certain activation or threshold energy, and chemical reactions, like those that occur during the muscle contractions ...

Famous quotes containing the words reactions and/or chemical:

    Prolonged, indiscriminate reviewing of books is a quite exceptionally thankless, irritating and exhausting job. It not only involves praising trash but constantly inventing reactions towards books about which one has no spontaneous feeling whatever.
    George Orwell (1903–1950)

    We are close to dead. There are faces and bodies like gorged maggots on the dance floor, on the highway, in the city, in the stadium; they are a host of chemical machines who swallow the product of chemical factories, aspirin, preservatives, stimulant, relaxant, and breathe out their chemical wastes into a polluted air. The sense of a long last night over civilization is back again.
    Norman Mailer (b. 1923)
