Why is chemical equilibrium dynamic?
Because there are many factors that can change the Products/Reactants ratio!
Chemical equilibrium refers to the balance between products and reactants after a given reaction has reached a state of order, in which both reactants and products are forming at a constant rate. It is dynamic because there are many factors that affect what that ratio will be, as defined by LeChatelier.
Affects the solubility of the products / reactants, yet also will change the equilibrium constant if the reaction is exothermic or endothermic. This is the case because at different temperatures, more products or reactants may exist in solution.
If there is a very large concentration of either a product or reactant, it will shift the equilibrium one way or the other. This is because the addition of reactants or products will always yield a reaction one way or the other, unless the reaction can no longer dissolve any more of it. In that case, it becomes a precipitate which does not effect equilibrium
This affects gaseous products and reactants. The side where there is more gas is the side in which the equilibrium will shift to if the pressure is decreased, because more can fit now. Vice versa as well.
There are many factors that shift equilibrium (Kc) so we must always be wary of these factors before we jump to a conclusion about what the equilibrium is, because it is very dynamic!
Good question....we can approach the answer on the basis of
We write the general equilibrium as:
As with any reaction there is a rate forward,
Now, by definition, the chemical condition of equilibrium is defined when the forward and reverse rates are equal:
And upon rearrangement,
And the quotient
There should be many answers here that deal with equilibria. If there is a specific problem or query, ask, and someone will help you.
