In equilibrium, stress means the manner in which equilibrium is altered, and shift represents which direction the equilibrium will move to compensate for the stress.

When equilibrium shifts to the reactants in response to stress how is the equilibrium position changed?
When the concentration increases, the equilibrium shifts away from the substance. Equilibrium is based on the molarity of the reactants. Increasing concentration increases the amount of that reactant in the solution.
If a change is made to a system in equilibrium the equilibrium will shift to oppose the change.?
Yes, this is the principle of Le Chatelier.
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
How does reaction quotient predicts the direction of a reaction?
The reaction quotient is the ratio of products to reactants not at equilibrium. If the system is at equilibrium then Q becomes Keq the equilibrium constant. Q = products/reactants If Q < Keq then there are more reactants then products so the system must shift toward the products to achieve equilibrium. If Q > Keq then there are more products than reactants and the system must shift toward the reactants to reach equilibrium.
How can a chemical reaction shift toward the desired direction?
You can make it shift, by Le Chatliers principle. Or. By Reaction Quotient method and comparing it against the Equilibrium constant.
What does Le Chtelier's principle say about upsetting a system at equilibrium?
Le Chatelier principle says, if a restriction is applied to a system in equilibrium, the system adjusts to a new equilibrium that tends to counteract the restriction. When equilibrium is under stress it will shift to relieve that stress. or all concentrations would change.
What is stress-shift?
stress shift is emphasis on a perticular word
When equilibrium shifts to the reactants in response to stress how is the equilibrium position changed?
When the concentration increases, the equilibrium shifts away from the substance. Equilibrium is based on the molarity of the reactants. Increasing concentration increases the amount of that reactant in the solution.
What happens to the equilibrium price and equilibrium quantity in a market if the demand curve shifts to the right?
If the demand shift to the right, the equilibrium price and quantity will shift from the initial equilibrium price and quantity to the next, i mean the equilibrium price and quantity will increase as compare to the first.
What does Le Châteliers principle state?
Le Chatelier's principle essentially states that if a stress is imposed on a system at equilibrium, the equilibrium will shift to minimize the stress. These stresses include: -Change in temperature -Change in pressure/volume (for gases) -Change in concentration A simple example of this: N2(g) + 3 H2(g) ⇌ 2 NH3(g) ΔH = −92kJ/mol -If you add N2(g) or 3 H2(g) the equilibrium will shift to the right (to the products), and more NH3(g) will be created so as to minimize the stress. - If you add NH3(g), the equilibrium will shift to the left (to the reactants), and more N2(g) and H2(g) will be created. -If you increase the temperature, the equilibrium will shift to the left (to the reactants). The reason for this is that the above reaction is exothermic, and releases heat. Consequently, the heat is on the side of the products, and thus if you add heat, the equilibrium will shift to the reactants and more N2(g) and H2(g) will be created. - If you increased the pressure, which is the same as decreasing the volume, the reaction will shift to the side with fewer moles, which, in this case, is the products. Thus, more NH3(g) will be created. -Conversely, if you decrease the pressure (increase the volume), the reaction will shift to the side with a greater number of moles, which, in this case, is the reactants. Thus, more N2(g) and H2(g) will be created. *It is important to note that changing pressure and volume only effects the equilibrium in gaseous reactions!

What does Le chateliers principal say about upsetting system at equilibrium?
A system of whose equilibrium has been upset will shift to restore equilibrium.
If a change is made to a system in equilibrium the equilibrium will shift to oppose the change.?
Yes, this is the principle of Le Chatelier.
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.
How do you predict shifts in equilibrium?
If you increase the amount of a substance, the equilibrium shifts away, if you decrease or get rid of something the equilibrium shifts to it, and if the substance that is changed is on both sides then the equilibrium doesn't shift.
What is stress shifts?
stress shift is emphasis on a perticular word
Will a 1997 Dodge truck automatic transmission fit a 1995 Dodge truck?
It would bolt up, but it will not shift. The shift control systems are different.It would bolt up, but it will not shift. The shift control systems are different.
