There are many things that we do today involves the subject of chemistry. One application from Chemistry is Kinetics or the Rates of Reactions. Rates of reactions is a topic wherein one finds or learns how fast does a chemical reaction to occur or to produce their respective products. These rates depend on the various chemicals or reactants one uses, including their internal and external environments.
One example of a chemical reaction that involves kinetics or rates of reactions is the rate of explosion of fireworks from the ground to the sky. In this chemical reaction, the person who creates fireworks have to use various kinds of metals to produce different colors (i.e. calcium chloride can produce the color orange). These people have to also measure the rate for the firework to explode at a certain height from the ground to the air for it to explode, and eventually, admired by the people watching.
Rate is measured here in terms of the time it takes for the reaction to take place; at the same time, the rate for it to explode in the air. This can be seen when the fireworks shows its colors in the sky, and thus the reaction has already happened. Basically, it is a combustion reaction of a metal with a non-metal or producing a salt (i.e. lithium salts).
