What determines the direction of a spontaneous change in chemical or physical processes?

Options

  1. AThe rate of the reaction.
  2. BThe unidirectional flow of heat.
  3. CThe potential to proceed without the assistance of an external agency.
  4. DThe temperature of the system.

Correct answer

B. The unidirectional flow of heat.

Step-by-step solution

The direction of a spontaneous change in chemical or physical processes is determined by the unidirectional flow of heat, which typically goes from higher temperature to lower temperature.
