Contact Action (Noun)
Meaning
Acceleration of a chemical reaction induced the presence of material that is chemically unchanged at the end of the reaction; "of the top 50 commodity chemicals, 30 are created directly by catalysis and another 6 are made from raw materials that are catalytically produced".
Classification
Nouns denoting natural processes.
Examples
- The presence of a catalyst enabled the contact action that accelerated the chemical reaction.
- Catalysts increase the rate of a chemical reaction by lowering the activation energy required for the contact action.
- The definition of a catalyst is a substance that speeds up a chemical reaction by providing an alternative reaction pathway with a lower activation energy and is chemically unchanged at the end of the contact action.
- The mechanism of contact action involves the formation of a precursor complex, which then transforms into the transition state and subsequently breaks apart to form the products.
- In heterogeneous catalysis, the catalyst is a solid substance and the reactants are gases or liquids, which interact with the solid catalyst through a contact action at its surface.
