Chemical equilibrium

• What is chemical equilibrium?

  A state where the concentrations of reactants and products remain constant
• What does dynamic equilibrium mean?

  It means the concentrations of reactants and products stay the same over time
• In what type of system can chemical equilibrium occur?

  In a closed system
• What does Le Chatelier's principle predict?

  It predicts how a system at equilibrium will respond to changes in conditions
• How does increasing pressure affect equilibrium in a chemical reaction involving gases?

  It shifts the equilibrium to the side with fewer gas molecules
• What happens to equilibrium when the concentration of a reactant is increased?

  The equilibrium shifts to the right to reduce the extra reactant
• What is the effect of decreasing the concentration of a reactant on equilibrium?

  The equilibrium shifts to the left to compensate for the decrease
• How does increasing temperature affect equilibrium in an endothermic reaction?

  It shifts the equilibrium in the endothermic direction
