Master Equilibrium Concepts

• Equilibrium occurs when the forward and reverse reactions are occurring at the same rate. (correct)
• Equilibrium occurs when the concentration of reactants is higher than the concentration of products.
• Equilibrium occurs when the concentration of products is higher than the concentration of reactants.
• Equilibrium occurs when the reaction has come to a complete stop.

• Temperature
• Pressure
• Concentration of reactants
• All of the above (correct)

• The principle that states that a system at equilibrium will respond to a stress by shifting in the direction that relieves the stress. (correct)
• The principle that states that a system at equilibrium will not respond to any stress.
• The principle that states that a system at equilibrium will respond to a stress by shifting in the opposite direction.
• The principle that states that a system at equilibrium will respond to a stress by shifting in the direction that increases the stress.
