We can also time how quickly reactants are used up the quicker these things happen, the faster the rate of the reaction if a reaction has. Chemical reactions on the basis of rate of reaction fast/instantaneous reactions chemical reaction which completes in less than ips (10-12 s) time, is known as fast reaction. A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another classically, enzymes increase the rates of biochemical reactions, so that metabolic syntheses and decompositions impossible under ordinary conditions can occur at the temperatures and concentrations present within a cell. Rate of reaction the rate of a reaction is the speed at which a chemical reaction happens if a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate.

A method that has recently been used to examine the rate of molecular transport across a phase boundary—statistical rate theory— is extended to obtain the expression for the rate of a single step chemical reaction the concentration dependence of the newly derived rate expression leads to the prediction of a higher reaction rate in the period immediately after the reaction has begun than any of the previous theories and gives a different physical interpretation of the ‘‘rate constant.

Rates of reaction the rate of a reaction can be measured by the rate at which a reactant is used up, or the rate at which a product is formed the temperature, concentration, pressure of reacting gases, surface area of reacting solids, and the use of catalysts, are all factors which affect the rate of a reaction.
