An absorbing reaction is likely to start spontaneously because it typically involves the release of energy, which drives the process forward. This energy release can lower the system's overall free energy, making the reaction thermodynamically favorable. Additionally, factors such as increased entropy or the stability of the products compared to the reactants can further promote spontaneity. Overall, these thermodynamic principles create a natural inclination for the reaction to occur without external input.
Lighting a sparkler is considered a spontaneous reaction even though it doesn't start spontaneously because it can occur by itself, or without the influence of any external forces once it is given the necessary energy needed for it to begin the reaction.The lighting of a sparkler is a common example of a spontaneous reaction which is often given in Science textbooks and exams around the world. The above is an example worth knowing.
The amount of energy required to initiate a chemical reaction is known as the activation energy. This energy is necessary to break the bonds in the reactants and allows the reaction to proceed to form products. Activation energy varies widely between different reactions and can be influenced by factors such as temperature, concentration, and the presence of catalysts. In general, higher activation energy means that the reaction is less likely to occur spontaneously at a given temperature.

It indicates how likely a reaction might be, but there are no hard rules. Low activation energy indicates that the reaction is likely to take place spontaneously. In most cases, the reaction must be exothermic as well. There are lots of exceptions to these simple rules. For any reaction to occur, the reactants must gain at least the activation energy.
Activation energy is needed to overcome the energy barrier between the reactants and the transition state in a chemical reaction. It provides the initial push required to initiate the reaction by destabilizing the existing bonds in the reactant molecules. Once this energy barrier is surmounted, the reaction can proceed spontaneously to form the products.
An energy-releasing reaction is more likely to start spontaneously. You have to have enough energy to overcome the activation energy barrier (that is to start breaking some bonds). - See more at: http://www.chacha.com/question/what-makes-proteins-the-ideal-types-of-compounds-to-act-as-enzymes#sthash.WWgf8a0I.dpuf

The activation energy of a chemical reaction can be likened to pushing a car up a hill before it can roll down to the other side. Just like how the initial push is needed to start the motion, the activation energy is required to initiate a chemical reaction. Once the reaction is started, it can proceed spontaneously.

I believe they get their from the Sun to start the reaction :)oxygen
