Equilibrium

• What is dynamic equilibrium?

  When forward and backward reactions are occurring at equal rates. The concentrations of reactants and products stays constant.
• What does Le Chatelier’s principle states?

  That if an external condition is changed equilibrium will shift to opposite the change.
• What is the effect of increased temperature on equilibrium?

  Equilibrium will shift to oppose this and move in the endothermic reaction to try to reduce the temperature by absorbing heat.
• What is the effect of decreased temperature on equilibrium?

  Equilibrium will shifta and oppose this and move in the exothermic direction to try to increase the temperature by giving out heat.
• What is the effect of a lower temperature on yield?

  A higher yield of product but slow rates of reaction.
• What is the effect of increased pressure on equilibrium?

  It will shift to the side with fewer moles of gas to oppose the change and decrease pressure.
• What is the effect of decreasing reassure on equilibrium?

  It shift to the side with more moles of gas to oppose the change and increase pressure.
• What does high pressure lead to?

  High energy costs for pumps and high equipment costs.
