Temperature and reversible reactions

• What principle is discussed in relation to equilibrium?

  Le Chatelier's principle
• What does Le Chatelier's principle state?

  The system responds to counteract changes
• What happens during an exothermic reaction?

  Energy is released, increasing temperature
• What occurs when the reverse reaction takes place?

  Energy is taken in, decreasing temperature
• Are all reversible reactions the same regarding exothermic and endothermic properties?

  No, they can differ
• What happens if the temperature of the system is increased?

  The equilibrium shifts to the left
• Why does the equilibrium shift to the left when temperature increases?

  To reduce temperature by favoring endothermic reaction
• What happens to the amount of no2 when temperature increases?

  It increases
• What happens to the amount of n2o4 when temperature increases?

  It decreases
• What occurs if the temperature of the system is decreased?

  The equilibrium shifts to the right
• Why does the equilibrium shift to the right when temperature decreases?

  To increase temperature by favoring exothermic reaction
• What happens to the amount of n2o4 when temperature decreases?

  It increases
• What happens to the amount of no2 when temperature decreases?

  It decreases
