Factors affecting reaction rates

Second-order reactions are chemical reactions that are dependent on the concentrations of either two first-order reactants or one second-order reactant. Because second-order reactions can be any of the two types outlined above, their rates can be generalized as follows r=k[A]x[B]y Rate of Reaction : Let a reaction be – aA + bB cC + dD  […]

Enzyme inhibitors are chemicals that interfere with an enzyme’s catalytic function, slowing or stopping catalysis in some situations. Competitive, non-competitive, and substrate inhibition are the three most common kinds of enzyme inhibition. The existence of the enzyme-substrate complex ES is at the heart of most inhibition theories. The existence of transient ES structures has been

The formation and disappearance of chemical compounds are common phenomena. This happens when two or more substances react, and a new compound is formed. Sometimes the reaction is fast, and the compound is formed immediately; sometimes, it takes time, and sometimes, the compound is not formed at all.  The rates of formation and disappearance of

An increase in product concentration per unit time is proportional to a decrease in reactant concentration per unit time in a chemical reaction. The rate of a chemical reaction is also referred to as the rate of reaction. The rate at which the reaction takes place varies greatly from one person to another. As an

Basic introduction The rate of reaction may be defined as the speed at which the reaction proceeds. It is the rate at which products are formed or reactants are consumed during a reaction. The rate of reaction for products generally increases as the reaction proceeds. The amount of products increases and the amount of reactants

Putrefaction refers to a process of breaking down the body of an animal just like a human post-mortem (that means after death). In other words, it can be regarded as the decomposition of proteins, and the gradual breakdown of the cohesiveness between tissues, and the liquefaction of major organs. This is led by the decomposition

The reaction that appears to be an nth order reaction, whereas it belongs to some different order is known as the pseudo order reaction. These are the reactions that are generally not first-order but appear to be first order due to increased concentrations of one or more reactants than the other reactants. For example the

Promoter or Accelerators are those substances used to increase the activity of catalysts positively. These substances are also known as catalytic promoters. These substances or compounds are not truly catalysts, but when mixed in small quantities during the reaction and the catalyst, they enhance their efficiency. They differ from catalysts as a catalyst is a

Catalysts are substances, when added in any chemical reaction, alter or change the rate of an ongoing chemical reaction. In other words, catalysts are rate-changing factors of any chemical reaction. Catalysts are of two types–positive and negative.  Positive catalysts change the reaction rate by increasing the reaction rate, and negative catalysts change any chemical reaction

A Perkin reaction produces a beta unsaturated aromatic acid (‘beta unsaturated’ means it has a double bond), a carboxylic acid group by aldol condensation of an aromatic aldehyde group (meaning it has -CHO), and an acid anhydride in the presence of an alkali salt of the acid, which acts as a base catalyst to speed
