What happens when you add pressure to an equilibrium?
Other aspects of the system (such as heat) will change to maintain 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)
How does altitude affect phase change?
The change in pressure is highly affected by altitude.
What are three types of strees that can be applied to an equilibrium system?
What are three types of stress that can be applied to an equilibrium system?1. Temperature change2. Gas volume / pressure change3. Substance concentration change
What happens to the equilibrium if the pressure is increased?
equilibrium will shift to the side of the equation with the least moles in attempt to reduce pressure in the haber process N2+3H2 <--> 2NH3 an increase in pressure causes equilibrium to shift the right because it has the least moles (2 instead of 4) <--> represents a reversible reaction sign
According to le chatelier principle how would a change in pressure affect a gaseous system in equilibrium?
The answer is "The equilibrium would shift to reduce the pressure change" on Apex
How would a change in pressure affect a gaseous system in equilibrium, according to Le Chatelier's principle?
The answer is "The equilibrium would shift to reduce the pressure change" on Apex

How would Le Chatelier's principle a change in pressure affect a gaseous system in equilibrium?
The equalibrium would shift to reduce the pressure
Is it true that a change in pressure may affect the equilibrium position but has no effect on the equilibrium constant?
No.
How will a change in pressure and concentration affect the yield of ammonia made?
Per the Haber process, increasing the pressure moves the equilibrium position to the right, increasing the yield.
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.
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 three factors that can affect an equilibrium system?
A stress could be adding/taking away reactant/product. Or a change in temp and pressure (for gases). It depends on the system. Some of them get ulcers, but others just start drinking heavily. A system at equilbrium responds to a stress by shifting left or right (toward the reactants or toward the products) so as to minimize the effect of the disturbance. This is called LeChatelier's Principle. Some stresses can be a temperature change, a change in the concentration of one of the reactants or products, and a pressure change (if the reaction involves any reactants or products in the gaseous phase).

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.
