Question
I. After you open a bottle of soda, the drink eventually goes flat.
H+(aq)+HCO3?(aq)?CO2(g)+H2O(l)
How can Le Chatelier's principle explain this using the following reaction?
The escape of CO2 gas removes CO2; equilibrium favors the formation of the reactants. The soda no longer bubbles.
II. If the pI for a particular amino acid is 7.5, at which pH will the net charge on the molecule be zero?
The escape of CO2 gas removes CO2; equilibrium favors the formation of the products. The soda no longer bubbles.The escape of CO2 gas removes CO2; equilibrium favors the formation of the reactants. The soda no longer bubbles.
Explanation / Answer
When the bottle is opened the pressure decreases as the gas has essential the whole atmosphere to escape into. Now in a system in equilibrium, when this system undergoes a disturbance, the system will shift in such a way as to minimize the disturbance. This is known as le Chatelier
