An evaporating colloidal particle–laden droplet leaves behind a ring-like residue after drying. We routinely observe this ubiquitous phenomenon for dried coffee drops; thus, it is known as the "coffee ...

A controlled/"living" click polymerization method developed by researchers at the Institute of Science Tokyo and Nagoya ...

Discover interesting facts about the sun, the solar system's central star that supports all life on Earth.

Discusses the factors influencing chemical reaction rates and equilibrium. It explains how different reactions occur at varying rates due to factors such as the nature of reactants, surface area ...

When chemists design new chemical reactions, one useful piece of information involves the reaction's transition state -- the point of no return from which a reaction must proceed.

France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – a new record. The milestone was reached on February 12 at the Commissariat à l ...

Home | Chemistry | Rates of chemical reactions Rates of chemical reactions Understanding chemical reaction rate and the factors that affect it is essential to the production of chemicals for society.

Why do you think this works? The chemical reaction that happens in a light stick is slower when cold. Do you think that starting with warmer reactants increases the rate of other chemical reactions?

Key Concepts A catalyst is a substance that can help the reactants in a chemical reaction react with each other faster. A catalyst does not actually become part of the products of the reaction.

Assessing the validity of a driving-force-dependent kinetic theory for a unimolecular elementary reaction step is difficult when the observed reaction rate is strongly influenced by properties of the ...
