Detailed explanation-1: -A spontaneous process is one that develops on its own under specific conditions without assistance from outside sources and moves in a specific direction. Natural processes are always unplanned.
Detailed explanation-2: -A spontaneous process is one that occurs naturally under certain conditions. A nonspontaneous process, on the other hand, will not take place unless it is “driven” by the continual input of energy from an external source.
Detailed explanation-3: -Reason: Spontaneous process is an irreversible process and may be reversed by some external agency.
Detailed explanation-4: -Reason: Spontaneous reactions are invariably exothermic.
Detailed explanation-5: -A spontaneous change is unidirectional i.e. it takes place in only one direction. For the change to occur in reverse direction work has to be done. For a spontaneous change to occur, time is no factor. A spontaneous process may take place rapidly or very slowly.
