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.
Why does changing the concentration of reactant shift the equilibrium?
Le Chatlier's PrincipleIf an equilibrium reaction is occurring and some reactant from either side of the equilibrium is added, the reaction goes in a direction that is to oppose the addition of a reactant. For example. In the equilibrium of CO2 + H2O = H2CO3, if more CO2 is added then the equilibrium shifts in such a way that this change is opposed so more H2CO3 is produced. For more information, research Le Chatlier's Principle.
What would happen to a system at equilibrium if the temperature changed?
If the system is in equilibrium then the temperature is also.
How does temperature affect Keq of a reaction?
Changing the temperature will change Keq - apex (Explanation): Keq is closely related to temperature and is part of the equation, so changing temperature will change Keq. Temperature does speed up the reaction sometimes, but that is not the only thing that it can affect.
What does Le Chatelier's principle state?
A reaction at equilibrium will respond to balance a change - apex (Explanation): The answer is NOT "a new equilibrium ratio will form", because although this is true, it will not necessarily always happen and is not what le chatelier's principle is about. His principle focuses on the reaction changing to cancel out or balance the change in equilibrium. Therefore, this is the correct answer.
If the temperature of a reaction increases what happens to the value of the equilibruim constant?

What is the LeChatlier?
The Chatelier's Principle states that when a dynamic equilibrium is disturbed by changing conditions then the position of equilibrium shifts to counteract the change to reestablish equilibrium. A chemical reaction is at equilibrium and experiences a change in pressure, temperature, or concentration of products , equilibrium will shift in opposite directions to offset change.
What is meant by a stress on a reaction at equilibrium?
A change in the amount (or concentration) of at least one of the reactants and products or a change in temperature or pressure.
What information do you need to determine how a change in pressure will affect the equilibrium of a reaction?
The total number of moles of gas on each side of the reaction.
What effect does the removal of heat have on the equilibrium position?
The temperature of a reaction will entirely change th equilibrium position for any given reaction. If I'm right, as you increase the temperature, the equilibrium shifts closer to the endothermic reaction as there is more heat to consume. It may also, of course, change other properties of the substances involved in the reaction, but that depends on the chemicals.
What happen to the movement of molecules at equillimbrium?
The movement of molecules at equilibrium is determined by Le Chatalier's principle. This basically says that if you change a reaction to favour one side, the equilibrium will try and counteract this change. The three things that can affect an equilibrium is temperature, pressure and concentration.
Why does changing the concentration of reactant shift the equilibrium?
Le Chatlier's PrincipleIf an equilibrium reaction is occurring and some reactant from either side of the equilibrium is added, the reaction goes in a direction that is to oppose the addition of a reactant. For example. In the equilibrium of CO2 + H2O = H2CO3, if more CO2 is added then the equilibrium shifts in such a way that this change is opposed so more H2CO3 is produced. For more information, research Le Chatlier's Principle.
Can a catalyst change rate of reaction equilibrium position or both?
A catalyst cannot change the equilibrium position. However, it can change its rate.
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.
If a chemical reaction has reached equilibrium and you lower the pressure of the system while keeping the temperature constant what happens to the equilibrium of the reaction?
If all the reactants occupy more volume than all of the products, the reverse reaction will be favored. If all the reactants occupy less volume than all of the products, the forward reaction will be favored. If the products and reagents have the same volume, the equilibrium will not change.
Factor that can change equilibrium constant?
Temperature
What would happen to a system at equilibrium if the temperature changed?
If the system is in equilibrium then the temperature is also.
