reversible reactions

• What is a reversible reaction?

  A reaction that can go both forward and backward
• What is equilibrium in a reversible reaction?

  When forward and reverse reactions occur at the same rate
• How can the direction of a reversible reaction be changed?

  By changing the conditions, like temperature
• What is the effect of heating hydrated copper sulfate?

  It forms anhydrous copper sulfate and water
• What is the nature of the forward reaction when heating hydrated copper sulfate?

  The forward reaction is endothermic
• What happens in the reverse reaction of anhydrous copper sulfate?

  Energy is released, making it exothermic
• What is the relationship between exothermic and endothermic reactions in reversible reactions?

  If one direction is exothermic, the opposite is endothermic
• What is a key fact about energy transfer in reversible reactions?

  The same amount of energy is transferred in each direction
• What happens in a sealed container during a reversible reaction?

  Reactants and products cannot escape
• What is the significance of equilibrium in a reversible reaction?

  It indicates balanced rates of forward and reverse reactions
• What are the energy changes in reversible reactions?

  • Forward reaction: Endothermic (energy absorbed)
  • Reverse reaction: Exothermic (energy released)
  • Same energy amount transferred in both directions
• What are the key characteristics of reversible reactions?

  • Can proceed in both directions
  • Direction can change with conditions
  • Equilibrium occurs when rates are equal
