Question

Which is true for a liquid-gas equilibrium having an equilibrium constant K?

• A. K is dependent on temperature
• B. Pressure doesn’t affect amount of gas
• C. matter is not exchanged at the interface
• D. all of the above

Answer 1

Answer: (A)

The equilibrium constant of a chemical reaction is the value of the reaction quotient when the reaction has reached equilibrium. An equilibrium constant value is independent of the analytical concentrations of the reactant and product species in a mixture, but depends on temperature and on ionic strength.
