Reversible reactions

• What are reversible reactions?

  Reactions where products can form reactants
• How do reversible reactions function?

  Products can react to form reactants again
• What does the symbol $A +$$B \rightleftharpoons C +$$D$ represent?


  It represents a reversible reaction
• What happens when ammonium chloride is heated?

  It breaks down into ammonia and hydrogen chloride
• What occurs when ammonium chloride cools after being heated?

  It reverts back to solid ammonium chloride
• What is dynamic equilibrium in reversible reactions?

  It means reactions occur in both directions simultaneously
• What does it mean if a reversible reaction reaches equilibrium?

  Concentrations of reactants and products remain constant
• What does it mean for a system to be closed in the context of reversible reactions?

  No substances can enter or leave the system
• How can changing temperature affect a reversible reaction?

  It can shift the equilibrium position
• What happens to the rate of forward and reverse reactions at equilibrium?

  They occur at the same rate
• What does the term "dynamic" in dynamic equilibrium imply?

  Reactions are still occurring, but no net change
• What is the effect of changing pressure on a reversible reaction?

  It can shift the equilibrium based on gas volumes
• How can you increase product yield in a reversible reaction?

  By changing temperature or pressure conditions
• What does it mean for a reaction to be at equilibrium?

  Concentrations of reactants and products are stable
• How do forward and reverse reactions interact at equilibrium?

  They cancel each other out in terms of concentration
• What is the relationship between temperature and product formation in reversible reactions?

  Higher temperatures can favor product formation
• What is the significance of the equilibrium constant?

  It quantifies the ratio of products to reactants
• How does increasing concentration of reactants affect a reversible reaction?

  It shifts the equilibrium towards products
• What happens to the rates of reactions when equilibrium is disturbed?

  They adjust to restore equilibrium
• What does Le Chatelier's principle state?

  A system at equilibrium will adjust to counteract changes
• What is the effect of catalysts on reversible reactions?

  They speed up both forward and reverse reactions
• How can pressure changes affect gaseous reactions?

  They can shift equilibrium towards fewer gas molecules
• What is the relationship between reaction rates and equilibrium?

  Reaction rates determine the position of equilibrium
• What does it mean for a reaction to be reversible?

  It can proceed in both forward and backward directions

  It can shift the equilibrium towards the side with more particles
• What is the role of temperature in chemical reactions?

  It affects the rate and equilibrium of reactions
• How can you manipulate conditions to favor product formation in a reversible reaction?

  By adjusting temperature and pressure appropriately
• What happens to the equilibrium constant if the reaction is exothermic and temperature increases?

  The equilibrium constant decreases
• What does it mean for a reaction to be at dynamic equilibrium?

  Reactions continue to occur without net change
• What is the effect of increasing the concentration of products in a reversible reaction?

  It shifts the equilibrium towards the reactants
