THURSDAY'S SCRIBE

Hey guys excuse the late scribe, no net for me. On Thursday, most of you know we had somewhat of a review. In the beginning we were all "reminded" of what equilibrium was. IT IS WHEN THE RATE OF THE FORWARD REACTION = THE RATE OF THE REVERSE REACTION.

Necessities Include;
- must be a closed system
- applies only to a gas and aqueous reactions
- reversible
- dynamic
- rates are equal

That same day, we received a handout on Le Chatelier's Principle. remember he stated that "WHEN A SYSTEM IS SUBJECTED TO STRESS, THE SYSTEM WILL ADJUST SO AS TO RELIEVE THE STRESS." Also, there were various "rules" to follow to figure out if the product or reactant was favoured. Some factors included changing concentration, pressure changes and temperature changes. Don't forget what we were reminded several times, "TEMPERATURE IS THE ONLY FACTOR WHICH WILL CHANGE THE VALUE OF KC" Also, something tricky, adding a catalyst to a system, lowers the activation energy of both the forward and reverse reaction equally thus it will not effect the equilibrium position. Although, if it wasn't at equilibrium the catalyst would make the system reach equilibrium much faster.
