Which of the following statements regarding spontaneous process is NOT true?

Options

  1. AIt occurs of its own.
  2. BIt proceeds in both directions even in absence of external stimulant.
  3. CSpontaneity is not concerned with rate of reaction.
  4. DIt continues till equilibrium is reached.

Correct answer

B. It proceeds in both directions even in absence of external stimulant.

Step-by-step solution

A spontaneous process is one that occurs on its own without any external assistance. It is a unidirectional process, meaning it proceeds only in one direction under a given set of conditions. It cannot proceed in the reverse direction without the help of an external agency. Therefore, it does not proceed in both directions. Thermodynamics determines the spontaneity of a process but provides no information about the rate of the reaction (kinetics). A spontaneous process continues until the system reaches a state of
