I'm taking an awesome chemistry final tomorrow. So, I'm not a massive failure at this:
k=mol/liters
Kc can only determine by experiment , not by evaluations of equations. so when writting the eq of Kc= [] products /[reactants], do not use units for [], as Kc has no units. Kc, only affected by temperature...
The units for the equilibrium constant, K, depend on the specific reaction. However, K is dimensionless for gases, while for reactions involving concentrations, the units of K will depend on the stoichiometry of the reaction.
The formula is F = kx, so solving for "k", you get k = F/x; in other words, a force divided by a distance. In SI units, you would use newtons / meter.

What is the significance of the magnitude of equilibrium constant K?
The magnitude of the equilibrium constant, K, indicates the extent of a chemical reaction at equilibrium. A large value of K (>1) signifies that the reaction strongly favors the formation of products. In contrast, a small value of K (<1) indicates that the reactants are favored at equilibrium.
What stays constant at equilibrium?
At equilibrium, the concentration of reactants and products remains constant, as the rates of the forward and reverse reactions are equal. The equilibrium constant (K) also remains constant at a specific temperature. The Gibbs free energy of the system is at a minimum but remains constant at equilibrium.
What is the equilibrium constant of a reaction?
It is the ratio of the concentrations of products to the concentrations of reactants.
What does the equilibrium constant tell you?
The equilibrium constant (K) indicates the relative amounts of reactants and products at equilibrium in a chemical reaction. Specifically, it shows the ratio of product concentrations to reactant concentrations when the reaction has reached equilibrium. A large equilibrium constant suggests the reaction favors products, while a small equilibrium constant indicates a preference for reactants.
What generalizations about an equilibrium constant can be made if the value for K is large?
It will take a short time to reach equilibrium It will take a long time to reach equilibrium The equilibrium lies to the right The equilibrium lies to the left Two of these One of those answers...
What is the difference between q and K in determining an equilibrium constant?
K is the equilibrium constant, Q is a concentration.
What is the significance of the magnitude of equilibrium constant K?
The magnitude of the equilibrium constant, K, indicates the extent of a chemical reaction at equilibrium. A large value of K (>1) signifies that the reaction strongly favors the formation of products. In contrast, a small value of K (<1) indicates that the reactants are favored at equilibrium.
What is used to describe the conditions of a reaction at equilibrium?
The equilibrium constant (K) is used to describe the conditions of a reaction at equilibrium. It provides information about the relative concentrations of products and reactants at equilibrium.
What information does an equilibrium constant give about a reaction?
It tells whether products or reactants are favored at equilibrium
What stays constant at equilibrium?
At equilibrium, the concentration of reactants and products remains constant, as the rates of the forward and reverse reactions are equal. The equilibrium constant (K) also remains constant at a specific temperature. The Gibbs free energy of the system is at a minimum but remains constant at equilibrium.
What is the symbol for the equilibrium constant?
The symbol for the equilibrium constant is K.
Can the equilibrium constant equal zero?
No, the equilibrium constant (K) cannot equal zero. A zero equilibrium constant would mean that the reaction does not proceed in either direction, which contradicts the fundamental nature of chemical reactions to reach an equilibrium state.
Why does constant Kc in chemical equilibrium has no units?
The equilibrium constant Kc is a ratio of the concentrations of products to reactants, and these units cancel out to give a unitless value. It represents the equilibrium position of a reaction, regardless of the units used for concentration.
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.
What is used to describe the conditions of a reaction to equilibrium?
An equilibrium constant
What information does the equilibrium constant give about reaction?
The equilibrium constant (K) gives information about the extent of a chemical reaction at equilibrium. It indicates the ratio of products to reactants at equilibrium and can help predict the direction the reaction will proceed under certain conditions.
What information does the equilibrium constant give about a reaction?
The equilibrium constant, denoted as K, provides information about the extent to which reactants are converted into products at equilibrium. It is a ratio of the concentrations of products to reactants, raised to the power of their stoichiometric coefficients in the balanced chemical equation. A large K value indicates that the reaction favors products at equilibrium, while a small K value indicates that the reaction favors reactants.
