How do solids affect equilibrium in a chemical reaction?
Solids do not affect the equilibrium of a chemical reaction because their concentration remains constant and does not change during the reaction. Only the concentrations of gases and dissolved substances in a reaction mixture can affect the equilibrium position.
Why does a numerically large Keq mean that the products are favored in an equilibrium system?
A numerically large equilibrium constant (Keq) indicates that the equilibrium lies far to the right, with more products present at equilibrium than reactants. This means that the forward reaction is favored, leading to a higher concentration of products compared to reactants in the equilibrium state.
If an equilibrium mixture is cooled what will be the effect on the intensity of the mixture color?
Cooling the equilibrium mixture will shift the equilibrium towards the side favoring the formation of the reactants (endothermic direction). The intensity of the mixture color could decrease if the reactants are colorless or have a lighter color compared to the products.
How does ethanol evaporation affect the efficiency of a chemical reaction?
Ethanol evaporation can affect the efficiency of a chemical reaction by changing the concentration of reactants and products in the reaction mixture. When ethanol evaporates, the volume of the reaction mixture decreases, leading to a higher concentration of the remaining components. This can potentially alter the reaction rate and equilibrium, impacting the overall efficiency of the reaction.
What is the difference between dissociation constant and equilibrium constant?
The dissociation constant describes the extent to which a compound breaks apart into its ions in a solution, specifically for weak acids or bases. The equilibrium constant, on the other hand, describes the ratio of product concentrations to reactant concentrations at equilibrium for a chemical reaction.
How would the equilibrium concentration of H½O be affected by removing H½ from the mixture?
If you remove H½ from the mixture, the equilibrium will shift to the left to compensate for the loss, meaning more H½O will dissociate to reform some of the missing H½. This will increase the concentration of H½O in an attempt to restore equilibrium.
How do solids affect equilibrium in a chemical reaction?
Solids do not affect the equilibrium of a chemical reaction because their concentration remains constant and does not change during the reaction. Only the concentrations of gases and dissolved substances in a reaction mixture can affect the equilibrium position.
What if kc expression is greater than 1 in chemistry?
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
Why does a numerically large Keq mean that the products are favored in an equilibrium system?
A numerically large equilibrium constant (Keq) indicates that the equilibrium lies far to the right, with more products present at equilibrium than reactants.

Can you write a sentence with the word catalyst?
"She added the catalyst to the mixture, and within seconds the reaction had started."

Cooling the equilibrium mixture will shift the equilibrium towards the side favoring the formation of the reactants (endothermic direction). The intensity of the mixture color could decrease if the reactants are colorless or have a lighter color compared to the products.

What does equilibrium and equilibrium mixture mean?
A quantity that characterizes the position of equilibrium for a reversible reaction; its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
How does an equilibrium reaction respond to the addiof extra reactant?
The concentration or activity of the product(s) will increase, and if there is at least one other reactant than the added one that is required for the completion of the reaction, the concentration of such an unadded reactant will decrease. (If there were no available unadded reactant, the reaction would not technically have been in equilibrium at the start, even though it may have reached a steady state that can persist for a long time in the absence of changed conditions.)
What will happen to the mixture at equilibrium if the temperature is decreased?
The system will rebalance.
Why the reaction mixture does not have 50 percent reactants and 50 percent products at equilibrium position?
At equilibrium, the reaction mixture does not have 50 percent reactants and 50 percent products because the reaction has reached a dynamic state where the rates of the forward and reverse reactions are equal. This means that both reactants and products are continuously being formed and consumed at the same rate, leading to a constant concentration of reactants and products. The specific ratio of reactants to products at equilibrium is determined by the equilibrium constant for the reaction, which is unique to each reaction and depends on factors such as temperature and pressure.
Why should we cool the mixture in haber process?
To ensure that you have the more product which will be produced because the equilibrium will shift to produce it. This will produce heat and also more chemical product that you want in the equilibrium mixture.
