Ostwald's dilution law applicable to:

Correct answer: D. Weak electrolytes

  • A. All electrolytes
  • B. Strong electrolytes
  • C. Non electrolytes
  • D. Weak electrolytes

Explanation

Ostwald's dilution law relates the degree of ionisation of a weak electrolyte to its concentration and is derived using its equilibrium constant. It does not apply to strong electrolytes because they are already almost completely ionised and do not obey the law's assumptions.

About Rate Constant

The rate constant, k, connects reaction rate with reactant concentrations in a rate law and has a value fixed for a particular reaction at a given temperature. Questions involve determining k from rate data, identifying its units for different reaction orders, and applying the Arrhenius equation to temperature changes.
