reversible reactions

• What is a reversible reaction?

  A reaction that can proceed in both directions
• What is equilibrium in a reversible reaction?

  When forward and reverse reactions occur at the same rate
• What happens to energy in an endothermic reaction?

  Energy is absorbed from the surroundings
• What happens to energy in an exothermic reaction?

  Energy is released into the surroundings
• What is the result of heating hydrated copper sulfate?

  It forms anhydrous copper sulfate and water
• How does the direction of a reversible reaction change?

  By changing the conditions, like temperature
• What color is hydrated copper sulfate?

  Blue
• What color is anhydrous copper sulfate?

  White
• What does it mean if a reaction is exothermic in one direction?

  It is endothermic in the opposite direction
• What happens at equilibrium in a sealed container?
