How can one tell if a reaction has reached its equilibrium?

All motion ceases


What does the equilibrium constant tell you?

The equilibrium constant can tell us how the reaction is going. If the constant is grater than one there are more products than reactants, so the reaction os closer to completion. If the equilibrium constant is less than 1 it shows that there are a lot more products than reactants so the reaction has not really started yet.


How are reaction rate and equilibrium connected?

At equilibrium, the reaction rate of the forward reaction and the reverse reaction are equal to one another. This means that the products of the forward reaction are being made at the same speed as the products of the reverse reaction.


How does an equilibrium reaction respond to the addiof extra reactant?

The concentration or activity of the product(s) will increase, and if there is at least one other reactant than the added one that is required for the completion of the reaction, the concentration of such an unadded reactant will decrease. (If there were no available unadded reactant, the reaction would not technically have been in equilibrium at the start, even though it may have reached a steady state that can persist for a long time in the absence of changed conditions.)


When a reaction system is at equilibrium the rates of the reaction in the forward and reverse directions are?

Equal to one another. K= k1/k-1 where k1 is the forward reaction, k-1 is the backwards reaction and K is the equilibrium constant.


What is mean of dynamic equilibirum in chemistry?

An equilibrium is a "balance", if something is in equilibrium then it is in balance. To add "static" is an unnecessary tautology except in the case of a mechanical equilibrium with zero linear momentum.


What are the examples of equilibrium?

Every physical phenomenon is an example of equilibrium; whenever there is conservation ,if you look closer, there is equilibrium. The action reaction principle is one example.

When there is no difference in the concentration of a substance from one to another then what happens?

Dynamic equilibrium has been reached.


Why a reaction needs to take place at equilibrium?

Many chemical reactions, like combustion , go to completion and not to equilibrium. It is normally desirable to give a chemical reaction time to reach equilibrium in order you get the maximum yield of one or more products.


What effect does a promoter catalyst have on the position of the equilibrium?

By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.


If the equilibrium constant of a reaction is one what is the free charge?

Zero, if you mean what is the free energy change.
