Question

Which statement is true for a liquid/gas mixture at equilibrium?

• A. The equilibrium constant is dependent on temperature
• B. The amount of the gas present at equilibrium is independent of pressure
• C. All interchange between the liquid and gas phases has ceased
• D. All of the above
• E. None of the above

Answer 1

The correct option is A The equilibrium constant is dependent on temperature

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.
