The Arrhenius equation
|
||
|
The Arrhenius equation was used for determining the relationship between hydrogen production and temperature: lnRx=lnA+nlnS- Ea/RT (3) where Rx is hydrogen production rate; A is the Arrhenius pre-exponential factor; S is substrate concentration (g/l); R is the ideal gas constant (8.314 J/mol/K) and T is the absolute temperature(K); Ea is activation energy (kJ/mol). Éó¸åÈËÒâ¼û£º The n given in Eq. (3) is not defined. This section could use more explanation/discussion, e.g. what is the utility of deriving a parameter for this equation, in what range is it expected to valid, is it really reasonable to calculate an activation energy for a biological transformation, or should this be seen as a fully empirical model?
