Exothermic processes
Key Questions
-
Answer:
Take the example of formation of water from Hydrogen, Oxygen this reaction highly exothermic but kinetically slow
Explanation:
The reaction to proceed first the reactants have to cross their activation energy barrier so that they form products giving the energy. Hence catalyst or temperature of the process plays a role in reaction to proceed spontaneously
The other example is burning of LPG gas requires ignition for reaction to gets started even though reaction is spontaneous.
Here is a video that explains spontaneity and signs of enthalpy and entropy:

Answer:
see answer below
Explanation:
Exothermic reaction is a reaction that releases heat.
Examples are:
- combustion
- rusting
-nuclear fission
- acid/base neutralization
-elephant toothpaste experiment
-freezing water into ice cubes
-burning a candle
