* Constant-pH Ensemble, for derivation see @cite reed92a.
30
* For the constant pH reactions you need to provide the deprotonation and
31
* afterwards the corresponding protonation reaction (in this order). If you
32
* want to deal with multiple reactions do it multiple times. Note that there is
33
* a difference in the usecase of the constant pH reactions and the above
34
* reaction ensemble. For the constant pH simulation directily the
35
* **apparent equilibrium constant which carries a unit** needs to be provided
36
* -- this is equivalent to the gamma of the reaction ensemble above, where the
37
* dimensionless reaction constant needs to be provided. Again: For the
38
* constant-pH algorithm not the dimensionless reaction constant needs to be
39
* provided here, but the apparent reaction constant.
