NEETChemistryChemical Equilibrium
When is the expression for the equilibrium constant applicable?
Options
- AWhen concentrations are changing rapidly
- BWhen concentrations have attained a constant value at equilibrium
- CWhen initial concentrations are high
- 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.
