The order of a reaction in some species seems an obvious, trivial concept that all chemists master. However, in complex situations such as catalytic systems, the order of a reaction is not always that simple: it can be partial, negative and function of other parameters. In order to analyze...

The order of reaction with respect to a given substance (such as reactant, catalyst or product) is defined as the index, or exponent, to which its concentration term in the rate equation is raised.The sum of the powers of the concentrations of the reactants of a chemical...
Order of reaction: The sum of concentration terms on which the rate of a reaction actually depends as observed experimentally is called the order of the reaction i.e. the sum of the powers or exponents to which the concentration or pressure terms are raised in order to determine the rate ...
Chemistry in Everyday Life We use chemistry every day, even if we don’t realize it. When you bake cookies, chemistry changes the ingredients in the oven. Soap cleans your hands because of chemistry. Even brushing your teeth is a chemical reaction. Chemistry helps with cooking, cleaning, and...
The simplest, and most commonly used, type of multiplexing isduplexing, in which two genes are amplified in a single reaction. Typically, in a relative qPCR experiment designed to determine the fold change differences in gene expression, these will be a single gene ...
I eventually had to take a bridging course in chemistry in order to study biology at university and it turns out that chemical theory is really interesting. I still don't really like the physical side of things (as in the test tubes, not physical chemistry!) but reading about chemistry exp...
The University of Science and Technology of China uses p-methoxybenzyl alcohol as raw material and polystyrene sulfonyl chloride as the carrier to prepare p-methoxybenzaldehyde through the Komblum reaction using a solid-phase method. The solid-phase method is used to prepare p-methoxybenzaldehyde, whi...
In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio ofsolutein a solution to eithersolventor totalsolution. Concentration is usually expressed in terms ofmassper unitvolume. However, the solute concentration may al...
