. 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
- 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.
Hence, Option (C) is correct.
