No. A spontaneous reaction is one that will happen given enough time - it doesn't need any energy or enzyme to make it happen. For instance, the decomposition of carbonic acid (H2CO3) into water and carbon dioxide (H2O and CO2) is spontaneous. However, it can be reversed by an enzyme called carbonic anhydrase; it just takes energy.

No
This is a very fast reaction.
This is a very fast reaction.
How fast the reaction occurs.....A+
molecules move fast and could explode if fast enought
There are more particles in the area to react with it.
This is a very fast reaction.
This is a very fast reaction.
Not necessarily.
A very fast combustion. So, a very fast reaction.
The pulses on the fast laser will enable us measure the reaction time on the chemical reaction.
Fireworks

How fast the reaction occurs.....A+
Chemical, an explosion is essentially extremely fast combustion which is a chemical reaction.
molecules move fast and could explode if fast enought
Only after the measurement of the reaction rate. See the link below for details.
nuclear decay rates take more time and chemical reaction rates could happen fast.
