What is the relationship between the equilibrium constant K and the rates of the forward and reverse reactions?
The equilibrium constant is equal to the rate constant for the forward reaction divided by the rate constant for the reverse reaction.
How is an equilibrium constant KEQ calculated and what does the value for KEQ mean?
In Type 1 calculations, all species in the system are at equilibrium already, so there will be no changes in concentration. The value for Keq is calculated simply by “plugging” the values for equilibrium concentrations into the Keq expression and calculating. Answer: The Keq = 0.50 for this reaction.
What can you conclude about the relationship between equilibrium constant and the rate of the reaction?
There is no direct relationship between the rate of the reaction and the equilibrium constant. The only factor that affects the equilibrium constant is the temperature. The general expression of reaction rate is: R=k[Reactant]n and k here is the rate constant and NOT the equilibrium constant.
What does Keq greater than 1 mean?
When Keq > 1 (the greater than symbol points to the right towards, or products) energetically the reaction is sliding down the hill to get to products. When Keq < 1 (the less than symbol points to the left, or toward starting materials) energetically the reaction is climbing up the hill to get to products.
What is the difference between equilibrium constant and equilibrium expression?
The rates of the forward and reverse reactions are the same when this system is at equilibrium. This ratio is the equilibrium constant for the reaction, Kc. The ratio of the concentrations of the reactants and products is known as the equilibrium constant expression.
What does equilibrium constant tell you about rate of reaction?
The equilibrium constant expression is a mathematical relationship that shows how the concentrations of the products vary with the concentration of the reactants. If the value of K is greater than 1, the products in the reaction are favored. If the value of K is less than 1, the reactants in the reaction are favored.
