In a compound response, concoction harmony is the state wherein the two reactants and items are available in fixations which have no further inclination to change with time, so that there is no recognizable change in the properties of the system. Usually, this state results when the forward response continues at a similar rate as the turn around response. The response rates of the forward and in reverse responses are commonly not zero, yet equivalent. Along these lines, there are no net changes in the groupings of the reactant(s) and product(s). Such a state is known as powerful balance.
