Flashcard 1: Identify the effect of removing a product on an equilibrium system.
Answer: Shifts right to produce more product. Removing product drives forward reaction to replace it.
Flashcard 2: What is the effect of adding more product to an equilibrium system?
Answer: Shifts left to produce more reactant. Excess product drives reverse reaction to consume it.
Flashcard 3: Identify the effect of decreasing temperature on an endothermic reaction.
Answer: Shifts left, favoring reactant formation. Lower temperature opposes heat absorption in endothermic reactions.
Flashcard 4: What happens when temperature increases in an endothermic reaction at equilibrium?
Answer: Shifts right, favoring product formation. Higher temperature favors endothermic (heat-absorbing) direction.
Flashcard 5: What effect does decreasing temperature have on an exothermic reaction at equilibrium?
Answer: Shifts right, favoring product formation. Lower temperature favors heat-producing direction.
Flashcard 6: What is the effect of removing a reactant from an equilibrium system?
Answer: Shifts left, producing more reactant. Less reactant causes reverse shift to restore equilibrium.
Flashcard 7: What effect does increasing the concentration of products have on equilibrium?
Answer: Shifts left, favoring reactant formation. Excess product drives reverse reaction to consume it.
Flashcard 8: How does decreasing the concentration of reactants affect equilibrium?
Answer: Shifts left, favoring reactant formation. Less reactant drives reverse reaction to restore balance.
Flashcard 9: What is the effect of pressure changes on a system with equal moles of gas on both sides?
Answer: No shift in equilibrium position. Equal gas moles means pressure changes don't favor either side.
Flashcard 10: What is the effect of decreasing the volume of a gaseous equilibrium system?
Answer: Shifts to the side with fewer moles of gas. Smaller volume increases pressure, favoring fewer gas molecules.
Flashcard 11: What is the effect of adding more product to an equilibrium system?
Answer: Shifts left to produce more reactant. Excess product drives reverse reaction to consume it.
Flashcard 12: What happens when pressure increases in a system with no gaseous components?
Answer: No shift in equilibrium position. Pressure changes only affect systems with gaseous components.
Flashcard 13: What is the effect of adding a reactant to an equilibrium system?
Answer: Shifts right to produce more products. Additional reactant drives forward reaction to consume excess.
Flashcard 14: How does adding a reactant affect equilibrium in a reaction?
Answer: Shifts right to produce more products. More reactant drives equilibrium toward product formation.
Flashcard 15: What is the effect of removing a product from an equilibrium system?
Answer: Shifts right, producing more product. System compensates by making more of removed substance.
Flashcard 16: What happens when you increase the volume of a gaseous equilibrium system?
Answer: Shifts to the side with more moles of gas. Larger volume decreases pressure, favoring gas expansion.
Flashcard 17: How does decreasing pressure affect a gaseous equilibrium system?
Answer: Shifts to the side with more moles of gas. Lower pressure favors side producing more gas molecules.
Flashcard 18: What is the effect of increasing temperature on an equilibrium system?
Answer: Shifts to absorb heat, depending on endo- or exothermic nature. Heat acts as reactant or product depending on reaction type.
Flashcard 19: Identify the effect of decreasing the concentration of products in equilibrium.
Answer: Shifts right, favoring product formation. Less product drives forward reaction to restore balance.
Flashcard 20: What is Le Chatelier's Principle?
Answer: A system at equilibrium shifts to counteract applied changes. System responds to minimize disturbance by shifting equilibrium.
Flashcard 21: What happens when pressure decreases in a gaseous equilibrium system?
Answer: Shifts to the side with more moles of gas. Lower pressure favors side with more gas molecules.
Flashcard 22: Identify the effect of adding more reactant to an equilibrium system.
Answer: Shifts right to produce more product. More reactant drives forward reaction to consume excess.
Flashcard 23: How does adding a catalyst affect an equilibrium system?
Answer: No shift; only increases rate of reaching equilibrium. Catalysts speed both directions equally without shifting.
Flashcard 24: Identify the effect of decreasing temperature on an exothermic reaction.
Answer: Shifts right, favoring product formation. Lower temperature favors exothermic (heat-producing) direction.
Flashcard 25: Identify the effect of increasing temperature on an endothermic reaction.
Answer: Shifts right, favoring product formation. Higher temperature favors heat-absorbing direction.
Flashcard 26: What happens when pressure increases in a gaseous equilibrium system?
Answer: Shifts to the side with fewer moles of gas. System minimizes pressure by reducing gas molecules.
Flashcard 27: How does increasing pressure affect a gaseous equilibrium system?
Answer: Shifts to the side with fewer moles of gas. Higher pressure favors side with fewer gas molecules.
Flashcard 28: What is the effect of adding an inert gas to a constant volume system?
Answer: No shift in equilibrium position. Inert gas doesn't affect partial pressures at constant volume.
Flashcard 29: Identify the effect of adding a catalyst to an equilibrium reaction.
Answer: No shift; only increases rate at which equilibrium is achieved. Catalysts affect reaction rates equally in both directions.
Flashcard 30: What happens to equilibrium when temperature decreases in an exothermic reaction?
Answer: Shifts right, favoring product formation. Lower temperature favors exothermic (heat-releasing) direction.
