How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?

None. A catalyst affects only the rate of reaction, and if the reaction is already at equilibrium, the net rate of the reaction is zero and remains so after a catalyst is added.

What is the difference between dissociation constant and equilibrium constant?
Equilibrium constants aren't changed if you change the concentrations of things present in the equilibrium. The only thing that changes an equilibrium constant is a change of temperature. The position of equilibrium is changed if you change the concentration of something present in the mixture. According to Le Chatelier's Principle, the position of equilibrium moves in such a way as to tend to undo the change that you have made.
If an equilibrium mixture is cooled what will be the effect on the intensity of the mixture color?
The Mixture will become darker more intense color
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.
Why does a numerically large Keq mean that the products are favored in an equilibrium system?
Because it means that the equilibrium mixture contains more product than reactants.
What are four factors which affect the rate of chemical reaction?
Temperature, atmospheric pressure (normal circumstances would be 1atm), percentage uncertainty of the equipment, loss of heat to your surroundings, parallax when reading scales such as a thermometer. And basically any variables that can be changed to be more accurate e.g your using cm's instead of mm's. Hope that helps :)
How would the equilibrium concentration of H½O be affected by removing H½ from the mixture?
concentration decreases
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.
Can you write a sentence with the word catalyst?
"She added the catalyst to the mixture, and within seconds the reaction had started."

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.
If an equilibrium mixture is cooled what will be the effect on the intensity of the mixture color?
The Mixture will become darker more intense color
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.
What will happen to the mixture at equilibrium if the temperature is decreased?
The system will rebalance.
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.
What is the difference between homogeneous mixtures and heterogeneous mixtures?
In every point of a homogeneous mixture the concentration remains unalter, but the concentration is different for hetrogeneous mixture.
Why does a numerically large Keq mean that the products are favored in an equilibrium system?
Because it means that the equilibrium mixture contains more product than reactants.
Why does diffusion eventually result in equilibrium?
I will use the sugar cube example. Equilibrium is established as a result of diffusion. For example, consider placing a sugar cube into a beaker of water. As the sugar cube dissolves, the sugar molecules diffuse throughout the beaker When the beaker is left undisturbed, the concentration of the sugar molecules will eventually remain the same throughout the beaker. Thus, equilibrium is established due to the same concentration of the sugar molecules throughout the beaker.
