What can you calculate if you know the concentration of a reaction's products and reactants as well as the coefficients of each in the balanced equation?
the equilibrium constant
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.
What is used to describe the conditions of reaction at equilibrium?
At equilibrium the concentrations of reactants and productas remain constant.
What reaction is the equilibrium constant?
It is the ratio of the concentrations of products to the concentrations of reactants.
What is the equilibrium constant of the reaction?
It is the ratio of the concentrations of products to the concentrations of reactants.
What information does an equilibrium constant give about a reaction?
It tells whether products or reactants are favored at equilibrium
What are Kp aND KC?
Kc is the equilibrium constant of a chemical reaction; Kp is the equilibrium constant of a chemical reaction at constant pressure.

the equilibrium constant
What is used to describe the conditions of a reaction at equilibrium?
An equilibrium constant
What is used to describe the conditions of a reaction to equilibrium?
An equilibrium constant
In a reaction the equilibrium constant for the forward reaction is Kf and the equilibrium constant of the backward reaction is KB What is the relationship between Kf and KB?
Kb= 1/Kf (:
What happens when the equilibrium constant is zero for a reaction?
If the equilibrium constant is zero, the reaction canNOT (will NEVER) reach equilibrium, it can not react back because all products are 'removed' (= concentration is zero).
How can the magnitude of an equilibrium constant indicate the extent of a reaction?
The reaction proceeds to a very large extent if Kc >> 1. On the other hand, the reaction hardly proceeds if Kc << 1.
What indicates a small equilibrium constant?
A small equilibrium constant value means equilibrium will never establish or the amount of products in reaction mixture is negligible.
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
What does an equilibrium constant give about a reaction?
It tells whether products or reactants are favored at equilibrium
What does the value of the equilibrium constant indicate?
When a chemical reaction reach the equilibrium she can not continue spontaneously.
