Web10 okt. 2024 · The reaction quotient (Q) describes the state of a system with respect to equilibrium, and tells you if a chemical reaction will proceed, and if so, in what direction. Mathematically, it is the equlibrium constant expression, but using the concentrations of any system, whether it is at equilibrium, or not. For a chemical reaction to occur, Q ≠ K. In case 4, after five time constants the function reaches a value less than 1% of its original. In most cases this 1% threshold is considered sufficient to assume that the function has decayed to zero – as a rule of thumb, in control engineering a stable system is one that exhibits such an overall damped behavior.
