A non-spontaneous process needs a steady stream of energy to function, whereas a spontaneous process happens on its own (possibly requiring an initial energy input).
The scenario described above can be viewed as:
(a) A satellite falls to Earth.
Non spontaneous ( the process is not occuring naturally and is happening due to constant force of earth gravity.)
(b) Water decomposes to H2 and O2‚ at 298 K and 1 atm.
Non-Spontaneous (Water breaks down into H and O through the electrolysis process, so it is not spontaneous.)
H2O -------------------> H2 + O2
(c) Average car prices increase.
Non-spontaneous (it will increase due to a number of factors in accordance with market price values)
