Description: Chemical kinetics is also called reaction kinetics. In this video, we will understand the rates of chemical reactions and the order of reactions.

Question

If a finely divided solid or powder is used, there will be a greater number of solid particles available for reaction. As a result, the rate of the reaction will increase. For example, finely divided grain can combust explosively. This has led to a number of major explosions in confined spaces in grain factories.

Find out some examples from different locations around the world where this has happened.

Accepted Answer

A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidising gaseous medium, such as pure oxygen.

Dust explosions are a frequent hazard in coal mines, grain elevators, and other industrial environments. They are also commonly used by special effects artists, filmmakers, and pyrotechnicians, given their spectacular appearance and ability to be safely contained under certain carefully controlled conditions.

A gigantic explosion of flour dust destroyed a mill in Minnesota on May $2$ , $1878$ , killing $18$ workers at the Washburn A Mill and another four in adjacent buildings. Mount Mulligan mine disaster in Australia $1921$ . Explosion at Imperial Sugar in Port Wentworth, Georgia, US $2008$ .
