What does it mean to say that a reaction has reached equililibrium?
When a reaction has reached equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products remain constant over time, but the reaction is still ongoing.
How can one tell if a reaction has reached its equilibrium?
All motion ceases
How can one tell if a reaction as reached equilibrium?
A reaction has reached equilibrium when the concentrations of the reactants and products remain constant over time, indicating that the rates of the forward and reverse reactions are equal. This can often be observed through measurements of concentration, pressure, or color change, depending on the nature of the reaction. Additionally, the equilibrium constant (K) for the reaction can provide insight into the extent of reaction at equilibrium. If the ratios of the concentrations of products to reactants remain constant, the system is at equilibrium.
What factors doesn't change the equilibrium constant of a reaction?
The equilibrium constant of a reaction is unaffected by changes in concentration, pressure, or volume, as these do not alter the intrinsic properties of the reaction at a given temperature. Additionally, the equilibrium constant remains constant regardless of the presence of catalysts, which only speed up the rate at which equilibrium is reached but do not change the position of equilibrium itself. However, the equilibrium constant is temperature-dependent; a change in temperature will alter its value.
If a reaction is at equilibrium and you add reactants what happens?
If you continuously add reactants even after the reaction has attained the equilibrium then according to Le Chatelier's principle, the reaction will again proceed in forward direction in order to neutralise the reactants and once again the attain the state of equilibrium.

Does equilibrium favor the weaker acid in a chemical reaction?
In a chemical reaction, equilibrium does not favor the weaker acid. Equilibrium is reached when the rates of the forward and reverse reactions are equal, regardless of the strength of the acids involved.
What does the value of the equilibrium constant indicate?
The value of the equilibrium constant indicates the extent to which a reaction has reached equilibrium. A high value means that the equilibrium strongly favors the products, while a low value means the equilibrium strongly favors the reactants.
Does a large equilibrium constant mean that the reaction must be rapid?
Not necessarily. The equilibrium constant (K) quantifies the extent of a reaction at equilibrium, but it does not directly correlate to the rate of reaction. A large equilibrium constant indicates that the reaction favors the products at equilibrium, but the rate of the reaction depends on factors such as concentration, temperature, and catalysts.
How does the time it takes for equilibrium to be reached affected by temperature increases?
An increase in temperature can generally speed up the time it takes for equilibrium to be reached in a chemical reaction. This is because higher temperatures provide more energy to the reactant molecules, increasing their kinetic energy and collision frequency, which in turn accelerates the rate of the reaction towards equilibrium.
What information does an equilibrium constant give about a reaction?
It tells whether products or reactants are favored at equilibrium

How do you use the word equilibrium in a sentence?
In an organic chemical reaction, it is said to be in equilibrium , when the forward reaction is equal to the backward reaction. Here is an example. Ethanoic Acid and Ethanol are in equilibrium with water and ethyl ethanoate CH3COOH + CH3CH2OH H2O + CH3CH2-O-C(=O)CH3
If a reaction is at equilibrium and you add reactants what happens?
If you continuously add reactants even after the reaction has attained the equilibrium then according to Le Chatelier's principle, the reaction will again proceed in forward direction in order to neutralise the reactants and once again the attain the state of equilibrium.
