reversible reactions+ le chateliers principle

• Reversible reactions will reach

  equilibrium
• Reversible reactions go..

  both ways
• equilibrium is only reached if a reaction takes place in a...

  closed system
• What is meant by a closed system?

  A closed system is when none of the reactants or products can escape and nothing else can get in
• Which is greater when equilibrium lies to the right, concentration of products or reactants?

  products
• Which is greater when equilibrium lies to the left, concentration of products or reactants?

  reactants
• What does the position of equilibrium depend on?

  temperature

  pressure

  concentration of reactants and products
• Reversible reactions can be...

  endothermic or exothermic
• What does anhydrous mean?

  'without water'
• What is Le Chatelier principle?


  That if you change the conditions of a reversible reaction at equilibrium, the system will try to counteract that change
• What can le chateliers principle be used to predict?

  the effect of any changes you make to a reaction system
• if you decrease temp, equilibrium will move in the...

  exothermic direction to produce more heat
• if you increase temp, equilibrium will move in the...

  endothermic direction to decrease heat
