R

abbreviation for rex or regina, ‘king’ or ‘queen’. The initial letter is used in proceedings, especially English criminal proceedings, to indicate that the Crown is the plaintiff or, more usually, prosecutor: R v. Haddock In Scotland, prosecutions run in the name of Her (or His) Majesty's Advocate, hence cases are cited HMAv. McFable.

Recognizing that R/M is also known as the specific gas constant, [R.sub.s], then the ideal gas law can simply be expressed as P = [[rho].sub.0][R.sub.s]T.
where [D.sub.K] is the Knudsen diffusion constant, M is the molar mass, R (=8.314 J/mol/K) is the gas constant, [r.sub.k] is the pore radius in kerogen, T is the absolute temperature in Kelvin, and [P.sub.k] is the gas pressure in kerogen.
are the activation energy and preexponential factor for N[H.sub.3] oxidation, respectively; R is the gas constant. Figure 10 shows the correlation between the preexponential factor for the N[H.sub.3] oxidation reaction when the aging conditions are the same as that in the standard SCR reaction at the aging temperature of 700 [degrees]C.
With the calculated estimations by (11), (12) for the maximum values of [v.sub.m], it should be remembered that by modulus 1 mol, for example, for copper, according to the laws of molecular physics, is numerically 63.55 x [10.sup.-3] kg [10] (remember that the dimension of the mole enters the universal gas constant R).

[Q.sub.D] (mg/g) is the theoretical saturation capacity and e is the Polanyi potential, which is equal to [epsilon] = -RT ln(1 + 1 /[C.sub.e]) where R (R = 8.314 J/mol/K) is the gas constant and T (K) is the absolute temperature.
