Which of the following is an example of a gas-liquid equilibrium system?
The combustion of gasoline in a car engine
The reaction of baking soda and vinegar
The solubility of oxygen in water
The reaction of sodium and chlorine to form sodium chloride
A gas-liquid equilibrium system is a system where a gas is in equilibrium with a liquid, and the concentration of the gas in the liquid is determined by Henry's Law. The following options are not examples of a gas-liquid equilibrium system:
a) The combustion of gasoline in a car engine: This is a chemical reaction, not a gas-liquid equilibrium system.
b) The reaction of baking soda and vinegar: This is also a chemical reaction, not a gas-liquid equilibrium system.
d) The reaction of sodium and chlorine to form sodium chloride: This is a chemical reaction, not a gas-liquid equilibrium system.
However, the solubility of oxygen in water is an example of a gas-liquid equilibrium system, where the partial pressure of oxygen in the air is in equilibrium with the concentration of oxygen in the water, as determined by Henry's Law.
