Q27 / 120 · JEE Main 2007 · Chemistry

Identify the correct statement regarding a spontaneous process

  • Correct answer
    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

Solution

For a spontaneous process in an isolated system, the change in entropy is positive. Hence, (A) is correct.

Hence, the correct answer is option: 'A'.
