Web[The thermodynamic equilibrium constants in the left column refer to 3a to (3c), and Henry’s constant K H, whereby pK = –log K.]. Closed-Form Expression & Ionization Fractions. Once all activities in the formulas are expressed by concentrations (which can be done either for a dilute system or for conditional equilibrium constants), we are able to … WebFor a closed thermodynamic system, ... Thus one can state the amount of internal energy possessed by a thermodynamic system that one knows is presently in a given state, but one cannot tell, just from knowledge of the given present state, how much energy has in the past flowed into or out of the system as a result of its being heated or cooled ...

Many thermodynamic processes take place in so-called closed systems. This means that the mass of the gas does not change during the change of state. This is the case, for example, during the compression of air in an engine cylinder. Thus, the masses m 1 and m 2 can be equated in equation (\ref{1a}). …
