Reversible Reactions - Chemical Equilibrium
1. Describe what is meant by a reversible reaction and by equilibrium.
2. Describe the energy changes taking place in reversible reactions.
• If a reversible reaction is exothermic in one direction, it is endothermic in the opposite direction.
The same amount of energy is transfered in each case.
• At some point, the forward and the reverse reactions will take place at exactly the same rate. Scientists call the point equilibrium.
Temperature and reversible reactions
Describe the effect of changing the temperature on a reversible reaction at equilibrium.
• If a system is at equilibrium and a change is made to the conditions, then the system responds to counteract the change. Scientists call this the Le Chatelier's Principle.
Which way will the Equilibrium Shift? (Le Chatelier's Principle)
Describe the effect of changing the temperature on a reversible reaction at equilibrium.
• If a system is at equilibrium and a change is made to the conditions, then the system responds to counteract the change. Scientists call this the Le Chatelier's Principle.
