. Identify the correct statement regarding a spontaneous process

A: For a spontaneous process in an isolated system, the change in entropy is positive

B: Endothermic processes are never spontaneous

C: Exothermic processes are always spontaneous

D: Lowering of energy in the reaction process is the only criterion for spontaneity


Best Answer


  • Spontaneous process- if the entropy of a system increases and enthalpy decreases then that process is called a spontaneous process.
  • In an exothermic process energy the system decreases.

Final Answer:

Hence, Option (C) is correct.
