Differbetween
3 Answers. Here's a more simplistic response. Equilibrium position: a particular set of concentrations of reactant and product species. Equilibrium constant: a number that describes how far "forward" equilibrium lies for a particular system (as described by a particular equation).

What is meant by equilibrium constant?
The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change. ...
What is the difference between KC and QC?
Qc and Kc are calculate the same way, but Qc is used to determine which direction a reaction will proceed, while Kc is the equilibrium constant (the ratio of the concentrations of products and reactants when the reaction is at equilibrium).
What is the difference between Q and KSP?
Q=Ksp. The solution is saturated and at equilibrium. Q>Ksp. The solution is supersaturated, and ionic solid will precipitate.

Equilibrium and non-Equilibrium Conditions.
| Qsp/Ksp | Status |
|---|---|
| = 1 | System is at equilibrium; no net change will occur. |
What is the difference between rate constant and equilibrium constant?
The equilibrium constant is equal to the rate constant for the forward reaction divided by the rate constant for the reverse reaction. ... 1 lists the initial and equilibrium concentrations from five different experiments using the reaction system described by Equation 15.2.
What is the equilibrium constant dependent on?
The value of the equilibrium constant for any reaction is only determined by experiment. ... It does, however, depend on the temperature of the reaction. This is because equilibrium is defined as a condition resulting from the rates of forward and reverse reactions being equal.
What is equilibrium used for?
Chemical equilibrium reactions require reversible reactions that can form a dynamic equilibrium, these concepts are also covered here. The equilibrium constant is used to determine whether reactants or products are favoured in a reaction at chemical equilibrium.
What will happen when QC KC?
If Qc > Kc, The system has gone beyond the equilibrium. The ratio of concentrations is high. To reach equilibrium, products must be converted back into reactants. It means that the system must proceed from right to left to reach equilibrium.
What is the KC equation?
Kc is the equilibrium constant of a chemical reaction. ... For the reaction A+B=AB, the equilibrium constant Kc is defined as [AB]/[A][B]. Brackets denote reagent concentrations that must be given in order to compute Kc. As an example, we will calculate Kc for two reactions.
What happens when QC is less than KC?
When Qc is more than Kc, reactants would be formed to get that ratio back to equilibrium. When Qc is less than Kc, products would be formed to get the ratio up to equilbrium. When they are equal, it's at equilibrium.
What if Q is less than KSP?
If Q < Ksp, no precipitate will form. If Q = Ksp, a precipitate will form. If Q > Ksp, a precipitate will form. Note that precipitation may not happen immediately if Q is equal to or greater than Ksp.
What is the effect of catalyst on equilibrium constant?
Equilibrium constants are not changed if you add (or change) a catalyst. The only thing that changes an equilibrium constant is a change of temperature. The position of equilibrium is not changed if you add (or change) a catalyst. A catalyst speeds up both the forward and back reactions by exactly the same amount.
What does KSP mean?
Ksp (Solubility product constant) is the equilibrium between a solid and its respective ions in a solution. The value of the constant identifies the degree of which the compound can dissociate in water. For example the higher the Ksp the more soluble the compound is.
