How does le chatelier's principle describe an equilibrium's response to a stress?
Le Chatelier's principle states that when a stress is applied to a system at equilibrium, the system will shift in a way that minimizes the effect of that stress. This can involve changes in concentration, pressure, or temperature to restore equilibrium.
When equilibrium shifts to the reactants in response to stress how is the equilibrium position changed?
When equilibrium shifts to the reactants in response to stress, the equilibrium position shifts in the direction that helps counteract the stress applied. This can involve an increase in reactants or a decrease in products to restore equilibrium.
Can shifts in equilibrium systems be explained by considering the effect of a disturbance on a separate rates of forward and reverse reactions?
Yes, shifts in equilibrium systems can be explained by considering the effect of a disturbance on the rates of the forward and reverse reactions. When a disturbance occurs, the rates of the forward and reverse reactions can change, causing the system to shift in order to re-establish equilibrium. This shift helps to minimize the effects of the disturbance and restore the system to equilibrium.
Which way will equilibrium reaction shift if keg is large or small?
If the equilibrium constant (K_eq) is large, it means the products are favored at equilibrium. The reaction will shift toward the products to establish equilibrium. If K_eq is small, it means the reactants are favored at equilibrium. The reaction will shift toward the reactants to establish equilibrium.
Is it true that an example of a stress on an equilibrium is the increase of pressure in a closed system when the pressure of a reactant gas is increased from 1.0 ATM to 2.0 ATM?
Yes, increasing the pressure of a reactant gas in a closed system at equilibrium will shift the equilibrium towards the side with fewer moles of gas molecules to counteract the increase in pressure. This is in accordance with Le Chatelier's principle, which states that a system at equilibrium will adjust to counteract any external stress applied to it in order to reestablish equilibrium.
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 meant by a stress on a reaction at equilibrium?
A stress on a reaction at equilibrium refers to any change that disturbs the balance between reactants and products. This can include changes in temperature, pressure, or concentration. When a stress is applied, the reaction will shift in a direction that helps to relieve the stress and re-establish equilibrium.

When equilibrium shifts to the reactants in response to stress, the equilibrium position shifts in the direction that helps counteract the stress applied. This can involve an increase in reactants or a decrease in products to restore equilibrium.

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 happens when reactant is added to a system at equilibrium?
The equilibrium of the system will be upset.

Meaning of LeChatelier's Principle?
LeChatelier's Principle states that if a system at equilibrium is subjected to a change in temperature, pressure, or concentration, the system will adjust to relieve the stress caused by the change and shift the equilibrium in a direction that minimizes the impact of the change. In other words, the system will respond to counteract the disturbance and restore equilibrium.
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.
