Blog 9.2: LeChatelier's Principle

When HCL is added to the system the system shifted to the right to balance out the HCL indicted by the dark blue color change this means concentration of Cl- ion increased.

1. Since the system is exothermic when heated the heat is added to the reactant side of the system. This causes the system to shift to the right (indicated by dark blue color).
2. If the reaction is endothermic the reaction has more potential energy on the reactant side of the system. This means the heat of reaction has a positive sign because it is storing(gaining) energy. If the reaction is exothermic the potential energy decreases because it is being released in the form of heat this is shown on the product side of the system. This means the heat of reaction is negative because it i loosing energy.
3. Ag+ and Cl- when but together do not create a soluble compound according to table f. This was shown in the lab when mixing the silver with chlorine you are left with a cloud showing in the mixture showing they are creating a new compound and not mixing together. The solution around it was light pink this indicates a shift to the left decreasing Cl- to balance out the system.

Station 3 question:

1. When increasing pressure the gas bubbles in the soda go away to put the solution in equilibrium. When you decrease pressure you give more space for air bubbles to form to shift the system back into equilibrium. This is the same as when you open a soda you are decreasing the pressure of the soda inside the can so the formations of bubbles to balance out the can cause it to "effervesce" (release gas).

Enrichement:

1. Chickens pant out CO2 gas.
2. When the CO2 decreases the equilibrium of the system shifts to the right.
3. When the system shifts right it causes a decrease in the amount of CaCO3 (egg shell) produced by the chicken.
4. The panting resulting in thinner egg shells because as a result of having less CaCO3 produces less egg shell for the eggs this means the eggs have to have a thinner shell.
5. To insure their chicken produce normally think egg shells in warm weather farmer could air condition the chicken coupe. This takes advantage of Le Chatelier's Principle by manipulating the temperature of a system to achieve the results you want.
