When is the expression for the equilibrium constant applicable?

When is the expression for the equilibrium constant applicable?

Options

  1. AWhen concentrations are changing rapidly
  2. BWhen concentrations have attained a constant value at equilibrium
  3. CWhen initial concentrations are high
  4. DWhen no reactants are present

Correct answer

B. When concentrations have attained a constant value at equilibrium

Step-by-step solution

Expression for equilibrium constant is applicable only when concentrations of the reactants and products have attained a constant value at equilibrium state.
