Interpretation:
The terms spontaneous and instantaneous should be distinguished and examples have to be given.
Concept Introduction:
Any natural process or a
In
In non-spontaneous process, there is a requirement of external energy source. The free energy of the system increases. The entropy decreases in non-spontaneous process.
Explanation of Solution
Spontaneous process proceeds without outside intervention, whether a chemical or physical change is one that occurs by itself under specific conditions, without continuous input of energy from outside the system.
Example: The rusting of iron is an example of a process that is spontaneous but very slow.
Non-spontaneous process means the process states immediately and it takes a very short duration to occur. But spontaneous process does not mean that it will take short duration. It means that given enough time the process will happen by itself.
The ignition of gasoline is an example of a process that is not spontaneous but very fast.

- The SN 1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.
