Question
Identify the correct statement regarding a spontaneous process
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
Solution
For a spontaneous process in an isolated system, the change in entropy is positive.
