Eli5 – For an exothermic reaction, how do new bonds change temperature?

262 views

Take hydrogen peroxide decomposition for example. I get that it’s spontaneous and the products have less energy in the bonds than the reactants. How is the formation of these new bonds exactly increasing the kinetic energy of surrounding molecules? Is it some sort of light energy colliding with the molecules?

Think of the atoms like little magnets. When those magnets snap together, they move at a decent speed. When they collide it’s usually pretty violent, from all of that kinetic energy they picked up as they flew together.
