Theoretical Reaction
This chemical reaction is believed to be a time, temperature and pressure dependent process which creates liquid and/or gaseous hydrocarbon Hc from primary kerogen X and can be summarised using the formula:
where X0 is the initial kerogen concentration and X(t) is the kerogen concentration at time t.
It is generally held that the dependence on pressure is negligible, such that the process of catagenesis can be given as a first-order differential equation:
where X is the reactant (kerogen) and κ is the reaction rate constant which introduces the temperature-dependence via the Arrhenius equation.

Famous quotes containing the words theoretical and/or reaction:
“Post-structuralism is among other things a kind of theoretical hangover from the failed uprising of ‘68Ma way of keeping the revolution warm at the level of language, blending the euphoric libertarianism of that moment with the stoical melancholia of its aftermath.”
—Terry Eagleton (b. 1943)
“An actor must communicate his author’s given message—comedy, tragedy, serio- comedy; then comes his unique moment, as he is confronted by the looked-for, yet at times unexpected, reaction of the audience. This split second is his; he is in command of his medium; the effect vanishes into thin air; but that moment has a power all its own and, like power in any form, is stimulating and alluring.”
—Eleanor Robson Belmont (1878–1979)
