Does taking water out of an equilibrium reaction change the equilibrium constant?
No, the equilibrium constant is independent of concentration as long as the ratio of products and reactants remains as is. It can be effected by anything that would influence the ratio of products and reactants, such as changes in temperature or the addition of a catalysis.
What effect does the addition of NaOH have on the concentration of H?
say for example the equilibrium I2(aq)+H2O(l)-----HOI(aq)+I(aq)+H(aq) Think Lechatlier principle... addition of NaOH will cause the H ions to react with the OH ions to cause more water (more reactants) increase in reactants shifts the equilibrium in the FORWARD direction to form MORE H+ to restore the equilibrium
Assuming that the reaction is at equilibrium what effect does the addition of a catalyst have on the equilibruim?
a catalyst lowers the activation energy for both the forward and reverse reaction. however, it does not change the potential energy of the reactants or products. it also does not affect the heat of reaction (delta h)
What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
Does addition of noble gas effect partial pressures in gaseous equilibrium system?
Yes. If the pressure is increased, even with a noble gas, the reaction equilibrium will shift to alleviate and lower that increased pressure (if there are more moles of gas on one side of the reaction than the other).
What is effective action?
The mass action effect is the shift in the position of equilibrium through the addition or removal of a participant in the equilibrium.
Can you compare and contrast gradualism and punctuated equilibrium?
punctuated equilibria accounts for the gaps in the fossil record. Species evolve quickly during relatively short periods. Tiny changes in a species gradually add up to major changes over very long periods of time. Gradualism proposes that evolution occurs slowly but steadily. These periods of rapid change are separated by long periods of little or no change.
How does a system at equilibrium respond to the addition of more product?
Product added to a system at equilibrium will result in the reaction moving left, or using up product to make more reactants until it reaches equilibrium again.
How can the force table be used to demonstrate the addition of vectors using the principle of equilibrium?
:)))) Study!

Why addition and subtraction are important in our daily lves?
why addition & substraction important in our daily life

Why the direction of resultant vector in the triangle law of addition is reverse?
In order to bring the system to equilibrium, action and reaction cancel out. The resultant is the reaction.
What parameter involved in a chemical reaction will change with the addition of a catalyst?
The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.
How do you punctuate a song title within a quotation?
As always song titles should be properly punctuated regardless of it being in quotes. For songs ending in punctuation quote marks should be applied outside and in addition to those apostrophes.
What is mass action effect?
The law of mass action stipulate that the rate of a chemical reaction is directly proportional to the product of the activities (or concentrations) of the reactants.
