What does the value of the equilibrium constant indicate?
When a chemical reaction reach the equilibrium she can not continue spontaneously.
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 a very high value of Keq indicate?
That, at equilibrium, the reaction favours a high concentration of product and relatively less reactant.
Which of the following is the equilibrium constant of a reaction?
Keq = products/reactions

Which of the following factors does not affect thr equilibrium of a chemical reaction when it is changed?
The value of the equilibrium constant K is only influenced by temperature.
What does a very high value of Keq indicate?
That, at equilibrium, the reaction favours a high concentration of product and relatively less reactant.
The reaction quotient Q indicates?
Q indicates wether or not a reaction will occur when the value of Q is compared to the equilibrium constant K if Q is larger than K the reaction will occur from product to reactant (decomposition) if Q is smaller than K the reaction will occur from reactant to product
What happens when there is a very high k value in an equilibrium reaction?
Forward reaction favored, concentration of products is higher
Which of the following is the equilibrium constant of a reaction?
Keq = products/reactions
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 relative rate constant?
A relative rate constant the rate at which a reaction will take place. Ex. V = k [A][B] the constant ,k, is a constant value for the rate of the reaction in said equation.
Why the reaction mixture doesn't have 50 percents reactants and 50 percents products at equilibrium position?
Chemical equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. Take this example:2NO2(g) ↔N2O4(g)At this point of the reaction the rate of N2O4 produced from NO2 is the same as the rate of NO2 produced from N2O4. The key aspect to keep in mind is that the amounts (of moles) of products and reactants at equilibrium is not always 50%/50%. It is usually not.Finding the amounts of products and reactants present during a reaction can be found using Q. Q is known as the reaction quotient. Q can be found like so:Q=[products]/[reactants]reaction quotient =concentrations of products (M) / concentrations of reactantsQ is used to find this ratio at a certain point in time during a reaction (not atequlilibrium)Most likely, you will be given Keq, the equilibrium constant, for a reaction. The value tells you the concentrations of products/reactants at equilibrium. Comparing Q and Keqwill tell you whether a reaction is at equilibrium.Not to get off topic, the answer is that equilibrium does not mean that the reaction mixture has 50% reactants and 50% products. Equilibrium means that the rate of the forward reaction equals the rate of the reverse reaction.
What does a negative value for the standard potential indicate?
the negative value for a standard potential indicates that the reaction is not spontaneous.
