Progress go stat transportation mnWebA rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, where k is a proportionality constant called the rate constant and n is the order of the reaction with respect to A. gost barefoot chain link shoesWebMar 14, 2024 · The half-life of a second order reaction increase when concentration decreases because the formula is t1/2=1/k[A] and since the concentration is in the denominator, decreasing the concentration makes the denominator smaller and thus the overall fraction larger (for example 1/1000 to 1/100), this increases the half-life. go station train mapWebThe half-life formula is commonly used in nuclear physics where it describes the speed at which an atom undergoes radioactive decay. The formula for the half-life is obtained by dividing 0.693 by the constant λ. Here λ is called the disintegration or decay constant.
