Chemical stability when used in the technical sense in chemistry, means thermodynamic stability of a chemical system. Thermodynamic stability occurs when a system is in its lowest energy state, or chemical equilibrium with its environment.This may be a dynamic equilibrium, where individual atoms or molecules change form, but their overall number in a particular form is conserved.This type of chemical thermodynamic equilibrium will persist indefinitely unless the system is changed.his may be a dynamic equilibrium, where individual atoms or molecules change form, but their overall number in a particular form is conserved.

Rate base (utility) Rate base is the value of property on which a public utility is permitted to earn a specified rate of return, in accordance with rules set by a regulatory agency. In general, the rate base consists of the value of property as used by the utility in providing service.

Instead, public utility commissions (PUCs) set rates every few. years at a level sufï¬cient for the utility to recover costs and. earn a fair return on investment. However, actual utility.
