Phenomenological stoichiometric coefficient

The whole theoretical approach relies now on the abihty to calculate, for any condition of radiation field in the photobioreactor, the variables q, x, and x in a predictive manner. This calculation can be performed in two steps. First, it can be demonstrated (Dussap, 1988) that there are two non-adaptive conditions (ie, fixed conditions arising at the early stage of a cell s Hfe cycle), allowing us to obtain constant values for q and X- The first condition hnks the stoichiometric coefficient for the phosphorylation to the phenomenological stoichiometric coefficient in non-ideal coupling ... 

In this last work are present many interesting intuitions, there is an hypothesis of the microscopic interaction mechanism and from that and the stoichiometric coefficients a tiy to explain theoretically the exponential coefficients, previously arbitrary or purely phenomenological and there is a rruld use of thermodynamic data. 

The quantity dV/dA)A=o is known as the phenomenological coefficient of a reaction. It can be written as Vq/RT, where Vq is the exchange rate and the coefficient RT renders value A dimensionless. The affinity of a reaction is determined according to de Donder as the chemical (or electrochemical, for charged particles) potential difference of products (/) and initial substances (/), multiplied by the respective stoichiometric factors ...
