Multiple Choice Options

  • 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
