Which of the following best describes a spontaneous process in a closed system?

Options

  1. AA process that always occurs rapidly.
  2. BA process that occurs without any change in energy.
  3. CA process that occurs without the assistance of an external agency and tends to increase the system's entropy.
  4. DA process that can be reversed by some external agency.

Correct answer

C. A process that occurs without the assistance of an external agency and tends to increase the system's entropy.

Step-by-step solution

A spontaneous process in a closed system occurs without the need for external assistance and tends to increase the system's entropy, making it less predictable and more disordered.
