What is the order of reaction if the half life of a reaction is halved as the initial concentration of the reactant is doubled.?
Second order. If the half life of a reaction is halved as the initial concentration of the reactant is doubled, it means that half life is inversely proportional to initial concentration for this reaction. The only half life equation that fits this is the one for a second-order reaction. t(1/2) = 1/[Ao]k As you can see since k remains constant, if you double [Ao], you will cause t(1/2) to be halved.
A first-order reaction is 45 percent complete at the end of 35 minutes. what is the length of the half life of this reaction?
41
How do you calculate daughter in half life?
1000 years
What is the maximum rate costant of the reaction when the half life of a first order reaction at 27 degrees Celsius is 100 minutes10-6 percent of the reactant molecules exists in the activated state?
i am srry,it s 10^-6 (10 to the power -6)
What is the half-life of material?
i dont think it has 1..... if it does its a safe guess of millions of yearsAnswer:Half life is a concept used in connection with radioactive materials. it is the time required for half of the atoms to fission naturally. Steel is not radioactive.Some researchers use the term half-life as a measure of persistence in the environment or chemical reaction for any active material. In this sense the half-life of steel would be the time for half of the mass to oxidize or erode. With the various alloys which are called steel and the various conditions that they are exposed to there is no standard reference time frame for this reaction.

A first order reaction is found to have a rate constant t k equals .0000739 find the half life of this reaction?
Since the reaction is first-order, the half-life is constant and equals ln(2)/k, and the units of k are s-1. In this case, the half-life is ln(2)/(.0000739 s-1) = 9379.529 seconds.

Why half life of first order reaction does not depend upon the concentration?
half life of a chemical reaction is the time which is required and it does not depend upon concentration of reactantuired to convert hlaf of reactant into product and it depend upon the nature of reaction and condition of r
What is the formula for half-life?
In chemistry, the half-life of a reaction is defined as the time needed for the concentration of a reactant to decrease to half of its initial concentration. According to that definition, the half-life of the reaction will be t1/2 = 0,693/k where k is the equilibrium constant for that reaction at a specific temperature.
Why is radioactive decay measured in half lifes?
The half-life forms a type of clock used to calculate time passed.
How do you calculate daughter in half life?

What are some other uses of half-life?
it is use for radioactive substance to determine its age of reaction.
